Wiring to Control Terminals

Prerequisite: Control terminal connectors can be unplugged from the drive for ease of installation, as shown in
Types.
For details about safety functions wiring, refer to the chapter 6 Safety Functions. See
and the chapter Application Examples for typical control cable connections.
Keep control cables as short as possible and separate them from high-power cables to minimize interference.
1.
Loosen the screws for the terminals.
2.
Insert sleeved control cables into the slots.
3. Fasten the screws for the terminals.
4.
Ensure that the contact is firmly established and not loose. Loose control wiring can be the source of equipment faults or less
than optimal operation.

Enabling Motor Operation (Terminal 27)

4.9.3
A jumper wire is required between terminal 12 (or 13) and terminal 27 for the drive to operate when using factory default programming
values.
Digital input terminal 27 is designed to receive 24 V DC external interlock command.
l
When no interlock device is used, wire a jumper between control terminal 12 (recommended) or 13 to terminal 27. The jumper
l
provides an internal 24 V signal on terminal 27.
Only for GLCP: When the status line at the bottom of the LCP reads AUTO REMOTE COAST, it indicates that the unit is ready to
l
operate but is missing an input signal on terminal 27.

Default setting Description
– Analog input. Only voltage mode is supported. It can also
be used as digital input.
– Common for digital and analog inputs.
– Connected to digital/analog ground internally.
– RS485 interface. A control card switch is provided for ter-
mination resistance.
–
Form C relay output. These relays are in various locations
[1] Control Ready
depending on the drive configuration and size. Usable for
AC or DC voltage and resistive or inductive loads.
