Opto-Isolated Output Selection
Four independent programmable opto-isolated outputs are available on the J1 connector for
external monitoring of drive conditions. These outputs are available on terminals J1-19 thru J1-22.
These outputs require 5-30 VDC to operate. Each will sink up to 60mA maximum. The voltage drop
across the output may be as high as 1VDC (TTL compatible). These outputs may be configured as
shown in Figure 2-15. The output state for each of these outputs is programmed in the Output
(programming) Block. If the opto outputs are used to directly drive a relay, a flyback diode rated at
1A, 100 V minimum should be connected across the relay coil.
Name
Description of Opto-isolated Output
AT SETPOINT
Closed when motor speed equals setpoint command.
READY
Open if a fault exists or AC power is not applied.
ZERO SPEED
Closed when the motor speed is less than the user specified speed
threshold, otherwise open.
AT SPEED
Closed whenever the motor speed is within the user specified tolerance
band of the commanded speed, open outside tolerance band.
OVERLOAD
Closed when an RMS current overload has not occurred, open upon
overload.
KEYPAD CONTROL
Closed when the control is under LOCAL keypad control.
AT SET SPEED
Closed whenever the motor speed is above the user specified "set
speed", open below set speed.
FAULT
Closes when a FAULT is present.
FOLLOWING ERROR
Closed when the motor speed is outside the user specified tolerance
band of the Acc-Dec and S-Curve conditioned commanded speed.
Open when the motor speed is within tolerance band of conditioned
speed command.
DRIVE ON
Closed when the motor current has reached excitation level and capable
of producing torque.
CMD DIRECTION
Closed when reverse input direction command is received, open for
forward.
AT POSITION
Closed during a positioning command when the control is within the
tolerance band.
