5.11.5 Disconnecting the Control Cable from the Control Terminals

Procedure
1. To open the contact, insert a small screwdriver into the slot between the terminal holes and push the screwdriver inward.
2.
Pull gently on the wire to free it from the control terminal contact.

5.12 Enabling Motor Operation

If the status line at the bottom of the LCP reads AUTO REMOTE COAST, the unit is ready to operate, but is missing an input signal on
terminal 27. Digital input terminal 27 is designed to receive a 24 V DC external interlock command that allows the drive to operate
when using factory default programming values.
FACTORY-INSTALLED OPTIONAL EQUIPMENT
Do not remove factory-installed wiring to terminal 27. If the drive does not run, refer to the documentation for the optional
equipment that is wired into terminal 27.
Procedure
1.
When no interlock device is used, wire a jumper between control terminal 12 (recommended) or 13 to terminal 27.
This wire provides an internal 24 V signal on terminal 27. The drive is ready for operation.
