Wiring
General wiring diagram
(1) R1 relay contacts, for remote indication of the drive status.
(2) Internal + 24 VDC. If an external source is used (+ 30 VDC maximum), connect the 0 V of the source to the COM terminal, and do not
use the + 24 VDC terminal on the drive.
(3) Reference potentiometer (2.2 k
Ω) or similar (10 kΩ maximum).
(4) Optional braking module
(5) Optional braking resistor or other acceptable resistor.
Note:
• Use transient voltage surge suppressors for all inductive circuits near the drive or coupled to the same circuit (relays, contactors,
solenoid valves, etc).
• The ground terminal (green screw) is located on the opposite side in comparison with its position on the ER11 (see wiring trap label).
