█ Multiple Drives
Multiple drives can share the same mains power supply. Select MCCB, MC1 and F1 size according to
number of drives. Example. if 2 servo drives are connected, select double the rated MCCB and fuse.
Use a single point star connection from a single relay or strip terminal to distribute power to each servo
drive.
Connect noise filter NF1 individually for each drive.

Note
1. Use a separate NF1 noise filter in-
divitually for each servo drive. Only
connect the noise filter to the logic L1
L2 terminal.
2. For fuse F1, allow 1A per servo
drive connected.
3. Select circuit breaker (MCCB)
and magnetic contactor (MC1) with
enough capacity according to servo
drives connected.
4. Do not daisy chain the R S T or L1
L2 power conenction from one drive
to another.
5. A terminal block can be used in
place of a relay terminal.
