Cautions during Use
Follow instructions in ‘Cautions during Use'. Otherwise, it may cause unexpected accidents.
24VDC power supply should be insulated and limited voltage/current or Class 2, SELV power
supply device.
Re-supply power after min. 1 sec from disconnected power.
In case communication is unstable due to the noise generated by supplied power or
peripheral device, use ferrite core at communication line.
It is recommended to use 485 converter with the separate power.
(Autonics product, SCM-38I, recommended)
The thickness of cable should be same or thicker than the motor cable's when extending the
motor cable.
①
CN1 (power connector): AWG18
②
CN2 (motor+encoder connector): AWG22, AWG24
③
CN3 (I/O connector): AWG28
RS485 communication is for parameter setting and operation test instead of driver operation.
When operating with CC-Link, disconnect the RS485 communication from the device.
CC-Link dedicated cable must be used. The performance cannot be guaranteed in case of
using other cable.
Keep the distance between power cable and signal cable more than 10cm.
Motor vibration and noise can occur in specific frequency period
①
Change motor installation method or attach the damper.
②
Use the unit out of the dedicated frequency range when vibration and noise occurs
due to changing motor RUN speed.
For using motor, it is recommended to maintenance and inspection regularly.
①
Unwinding bolts and connection parts for the unit installation and load connection
②
Strange sound from ball bearing of the unit
③
Damage and stress of lead cable of the unit
④
Connection error with motor
⑤
Inconsistency between the axis of motor output and the center, concentric
(eccentric, declination) of the load, etc.
This product does not prepare protection function for a motor.
