Q1 | When communicating with the driver, can the LAN cable used to connect the PC to the internet be used without modification? |
---|---|
A1 |
It cannot be used as it is. Due to the different communication standards, the cable must be modified for RS-485.
|
Q2 | How to set parameters? |
A2 |
It can be set up by connecting the driver to a PC or PLC. Dedicated software is also available for PC.
|
Q3 | How long is the product lifetime? |
A3 |
The product lifetime varies depending on the usage environment and conditions. The guideline when used in the recommended atmosphere is 20,000 hours. Back to questions |
Q4 | Can it be used with a single-phase AC100V power supply? |
A4 |
Cannot be used. However, if only parameter setting changes are required, a single-phase 100 V power supply can be used. Back to questions |
Q5 | When can I use the simple hold function? |
A5 |
As it is an electric holding brake, it is suitable for temporary stopping applications during flow operations, e.g. on transfer conveyors.
|
Q6 | How much is the maximum temperature during normal use? |
A6 |
Although it depends on the conditions of use, the upper limit of the internal temperature for both the motor and driver is 100°C.
|
Q7 | Can drivers from other manufacturers be used? |
A7 |
Be sure to use the dedicated driver as it may cause trouble. Back to questions |
Q8 | How much is the backlash? |
A8 |
The backlash of the output shaft is 60 arcmins at a reduction ratio of 1/10, and 30 arcmins for others. Back to questions |
Q9 | If the power supply to the driver is switched off, is the stop position of the motor hold? |
A9 |
As this product does not use an absolute encoder for position recognition, if the power supply is cut off, the stop position when the power is restarted will be the origin.
|
Q10 | If equipped with a brake, can the brake be released without the intervention of the driver? Also, if the driver fails, can it be excited and released directly to the brake? |
A10 |
The brake can be released in direct connection with the 24 V power supply.
|
Q11 | Simple holding and short brake settings are possible as stopping methods, but how are they used? |
A11 |
Depending on the load, it can be used in different ways to prevent misalignment when stopped.
|
Q12 | Is the control between the PLC and the driver IO or serial communication (RS-485)? |
A12 |
Both communication methods are supported. Back to questions |
Q13 | How much is the holding torque of the simple hold function compared to the rated torque? |
A13 |
It is approximately 67% of the rated torque. Also, as this is only a simple hold function, holding is only for a short time (a few seconds).
|
Q14 | The connection between the PC and the driver fails. Where should I check? |
A14 |
Please check the following items.
|
Q15 | How much is the rate of speed fluctuation? |
A15 |
It will be approximately 0.5%. This represents the rate of change in the average speed of the motor when external conditions (e.g. load or temperature) change.
|
Q16 | How much is the maximum length of the extension cable connecting the motor and the driver? |
A16 |
Up to 10m. If an extension is considered, use a DCBL Hypoid Motor extension cable (sold separately). Back to questions |
Q17 | What kind of problems can be considered with longer cable? |
A17 |
If the length exceeds 10 m, it may be affected by noise and may not operate correctly.
|
Q18 | What faults can be expected if noise occurs in the communication between motor and driver? |
A18 |
There is a possibility that the position detection signal of the motor is misrecognized and the operating position is wrong (e.g. passing the stop position, stopping before the stop position, etc.).
|
Q19 | What problems can be expected if noise occurs in the input/output signal cable between the driver and control unit? |
A19 |
Signals may be misrecognized, resulting in unstable operation (e.g. motor starts/stops at unintended timing, output signal turns on/off at unintended timing). Back to questions |
Q20 | Which connector should I use for communication? |
A20 |
If you want to communicate while the motor is running, use the connector for RS-485 communication.
|
Q21 | When is a regenerative resistor required? |
A21 |
In lifting applications or when the inertia ratio is high, the motor may be turned from the load side to generate power and the overvoltage protection of the driver may be activated.
|
Q22 | How can motor extension cables be connected together? |
A22 |
The cable has male and female connectors on both ends, so it can be connected together using the cable connector. Back to questions |
Q23 | Can the communication cable CN3 beyond the 50 mm at the end of the cable be disconnected/connected? |
A23 |
The lead wires are loose wires, so they can be connected together by performing terminal processing, etc. Back to questions |
Q24 | Is the motor extension cable a flexible cable? |
A24 |
It is not a flexible cable. Back to questions |
Q25 | Is it possible to connect with a microUSB connector and operate while communicating? |
A25 |
The microUSB connector is mainly a port for writing parameters, etc.
|
Q26 | Is the motor driven by a DC power supply? |
A26 |
Despite the name DC brushless motors, these motors are driven by AC power.
|
Q27 | What is the difference from induction motors? |
A27 |
Generally, three-phase motors are controlled by open-loop control with an inverter.
|
Q28 | What is the difference from servo motors? |
A28 |
Servo motors are positioned as high-performance and multi-functional, but expensive.
|
Q29 | What conditions are necessary when selecting a DCBL Hypoid Motor? |
A29 |
Inquiry forms are posted at the end of the catalog and on our website, so please use them. Back to questions |
Q30 | How long exactly does the short time mentioned in the motor characteristics diagram in the catalogue, etc. refer to? |
A30 |
This will be a few seconds during acceleration and deceleration. Do not operate for long periods exceeding the rated rotation speed as this may cause abnormal heat generation. Back to questions |
Q31 | Is it possible to change the cable position? |
A31 |
It is possible in 90° pitch. See catalogue for more details. Back to questions |
Q32 | Can a reduction ratio of 1/80 or more be supported? |
A32 |
Available as a made to order product. Back to questions |
Q33 | Can parallel shaft type be manufactured? |
A33 |
Available as a made to order product. Back to questions |
Q34 | How often can the brakes be on/off? |
A34 |
Mechanical brake up to 10 times/min. Back to questions |
Q35 | Can the simple hold function be used in the same way as a servo lock? |
A35 |
Compared to servo motors, the pulse resolution is lower, so rapid start/deceleration performance is reduced.
|
Q36 | Is stopping accuracy improved compared to induction motor + inverter configurations? |
A36 |
The system is controlled using Hall sensor signals, so it can stop more accurately than an induction motor + inverter without feedback control.
|
Q37 | What voltage outputs does the driver support? |
A37 |
The output signal can support up to DC30V.
|
Q38 | If no brake is used, is the misalignment due to its own weight when stopped? |
A38 |
A simple hold function is available to prevent misalignment caused by its own weight for a short period of time (please refer to the parameter setting [Selection of stopping method] in the instruction manuals for setting instructions).
|
Q39 | What is the operating temperature for the Linipower Jack? |
A39 |
Motor and reducer parts are limited to 0 to 40°C and drivers to 0 to 50°C. Back to questions |
Q40 | Can it be used outdoors? |
A40 |
Although the motor part is IP65, it is not recommended for outdoor use. Please provide a cover or take other measures separately.
|
Q41 | Is it possible to change to a shaft made of a different material (e.g. stainless steel)? |
A41 |
Please contact us to discuss this, including your intended use. Back to questions |
Q42 | What problems can be expected when used in high temperature atmospheres? |
A42 |
The circuit board inside the motor may be damaged and the motor may stop running. Back to questions |
