5.7 H: Terminal Functions
The output closes when the motor is operating at the torque limit specified by the L7-oo parameters or an analog input. This
setting can only be used in OLV, CLV, AOLV/PM and CLV/PM control modes.
page 262 for details.
Setting 31: During Speed Limit
Note: PM motor control modes are not available on 600 V class drives, CIMR-Ao5oooooooo.
The output closes when the speed limit has been reached. This function can be used in CLV and CLV/PM control modes.
Status
Open The conditions described below are not present.
1. The frequency reference has reached the upper limit set in d2-01.
2. The frequency reference has fallen to the lower limit set in d2-02 or d2-03.
Closed
3. Parameter b1-05 is set to 1, 2, or 3, and the frequency reference has fallen below the minimum output frequency
(E1-09).
Setting 32: During Speed Limit in Torque Control
The motor torque and load torque are not in balance, causing the motor to accelerate. The output closes when the motor reaches
the speed limit. Refer to d5: Torque Control on page 178
details.
Setting 33: Zero Servo Complete
The output closes when Zero Servo is enabled and the load is locked into position within the allowable deviation (b9-02).
Refer to b9: Zero Servo on page 153
Setting 37: During Frequency Output
The output closes when the drive is outputting a frequency.
Status
Open Drive is stopped or one of the following functions is being performed: baseblock, DC Injection Braking, Short Circuit Braking.
Closed Drive is outputting frequency.
Setting 38: Drive Enable
Reflects the status of a digital input configured as a "Drive enable" input (H1-oo = 6A). If that digital input closes, then the
digital output set for "Drive enable" will also close.
Setting 39: Watt Hour Pulse Output
Outputs a pulse to indicate the watt hours.
Setting 3C: LOCAL/REMOTE Status
The output terminal closes while the drive is set for LOCAL and opens when in REMOTE.
Status
REMOTE: The external reference that has been selected (either b1-01 and b1-02 or b1-15 and b1-16) is used as frequency reference

and Run command source
Closed LOCAL: The digital operator is used as frequency reference and Run command source
