Block Title Parameter Description
OUTPUT OPTO OUTPUT
#1 – #4
Four optically isolated digital outputs that have two operating states, logical High or Low.
Each output may be configured to any of the following conditions:
Condition Description
Ready - Active when power is applied and no faults are present.
Zero Speed - Active when motor RPM is below the value of the Level 1 Output
“Zero SPD Set Pt” parameter.
At Speed - Active when output speed is within the speed range defined by
the Level 1 Output “At Speed Band” parameter.
At Set Speed - Active when output speed is at or above the Level 1 Output
“Set Speed” parameter.
Overload - Active during an Overload fault caused by a time out when
output current is greater than Rated Current.
Keypad Control - Active when control is in Local keypad control.
Fault - Active when a fault condition is present.
Following ERR - Active when the motor speed is outside the user specified
tolerance band defined by the At Speed Band parameter.
Motor Direction - Active High when REV direction feedback is sensed. Active Low
when FWD direction feedback is sensed.
Drive On - Active when control is “Ready” (has reached excitation level and
capable of producing torque).
CMD Direction - Active when Forward or Reverse is selected or enabled. Logical
output state indicates Forward or Reverse direction. High=FWD,
Low=REV.
AT Position - Active during an internal positioning command when control is
within the position band parameter tolerance.
Over Temp Warn - Active when control heat sink is within 3°C of Int Overtemp.
Process Error - Active when process feedback signal is outside the Level 2
Process Control block, PROC ERR TOL parameter value. Turns
off when process feedback error is within tolerance.
Drive Run - Active when drive is Ready, Enabled, Speed or Torque command
received with FWD/REV direction issued.
Serial – Active when in Serial mode.
Zero SPD Set PT Sets the speed at which the Zero Speed opto output becomes active (turns on). When the
speed is less than the ZERO SPD SET PT, the Opto Output becomes active. This is use-
ful when a motor brake is to interlock operation with a motor.
At Speed Band The At Speed Band serves two Opto Output Conditions and the Level 2 Protection block
Following Error:
Sets the speed range in RPM at which the At Speed opto output turns on and remains
active within the range.
Sets the Following Error Tolerance Band for the Level 1 OUTPUT, Opto Output condition
Following ERR. The opto output is active if the motor speed is outside this band.
Sets the allowable following error speed band. This value is used by the Level 2
Protection block, Following Error parameter (if it is set to ON). If the drive speed falls
out of this band, the Level 2 Protection block, Following Error parameter will shut
down the drive (if it is set to ON).
Set Speed Sets the speed that the AT Set Speed opto output becomes active (turns on). When the
speed is greater than the Level 1 Output SET SPEED parameter, the Opto Output
becomes active. This is useful when another machine must not start or stop until the
motor exceeds a predetermined speed.
