3.4 Motor connectors
Warning: High voltage may be present on the motor connector.
Before connecting or disconnecting the motor cable or touching the controller, turn
off all the power supplies and wait 10 minutes to allow the internal DC bus
capacitors to discharge.
Caution: The motor connectors must be insulated (no contact) from the power and the mains.
The motor connectors must always be correctly screwed onto the DSCDP to respect
the EMC standard.
Caution: The motor connectors must be handled in an ESD protected environment, only.
Remark: The motor cables connected to the DSCDP must be shielded (see §3.7.1
).
3.4.1 ETEL motor cables numbering system
ETEL standard motors cables are numbered according to the following system:
3.4.2 Connector JC7 and JC11: Motor connection
The DSCDP can drive single-phase, two-phase and three-phase motors. Connectors JC7 and JC11 enable
the supply of the motor phase(s).
(*): With two-phase motor, the current in 'motor phase 1- / 2-' is equal to (√2 x motor phase 1+) or (√2 x motor
phase 2+). Be careful to use the suitable cable diameter.
Remark: JC7 is used to connect the motor 1 and JC11 for the motor 2.
