1
+24 Vdc Supply
:
Powers the logic inputs to the drive. It is not intended
for it to be used to power external circuits. External use will void warranty.
2
Tie Point:
It has no internal connections and is used as a tie point for
the Motor Thermal or Stop button connection.
3
Run Input: When +24 Vdc is applied to this terminal, the Run relay picks
up, the Speed loop and the Current loop are enabled, and the clamp on
the SCR firing circuits is released.
4
Run Relay Contact Output: Normally Open connection. Rated:
0.5amps @ 120VAC for non-inductive loads. It can be used as the seal-in
contact in a three-wire run circuit or as the run contact feedback in a two-
wire system.
5
Run Relay Contact
: Relay common connection.
6
Run Relay Contact:
Normally Closed connection. Rated: 0.5amps @
120VAC for non-inductive loads.
7
Jog Input:
When +24 Vdc is applied to this input, the output of the
accel / decel circuit is electronically disconnected from the speed loop and
the jog speed command (from the jog speed pot) is electronically switched
jog speed command can be configured as a Thread speed
