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. Refer to H2-06: Watt Hour Output Unit Selection on page 223 for details.
Setting 3C: LOCAL/REMOTE Status
The output terminal closes while the drive is set for LOCAL and opens when in REMOTE.
Status Description
Open
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.
Setting 3D: During Speed Search
The output terminal closes while Speed Search is being performed. Refer to b3: Speed Search on page 153 for details.
Setting 3E: PID Feedback Low
Output terminal closes when a PID feedback loss (FbL) is detected. The feedback is considered to be lost if it falls below the
level set to b5-13 for longer than the time set to b5-14. Refer to PID Feedback Loss Detection on page 164 for details.
Setting 3F: PID Feedback High
Output terminal closes when a PID feedback loss (FbH) is detected. The feedback is considered to be lost if it rises beyond
the level set to b5-36 for longer than the time set to b5-37. Refer to PID Feedback Loss Detection on page 164 for details.
Setting 4A: During KEB Operation
The output terminal closes while KEB is being performed. Refer to KEB Ride-Thru Function on page 240 for a KEB function
description.
Setting 4C: During Fast Stop
The output terminal closes when a Fast Stop is being executed. Refer to Setting 15, 17: Fast Stop (N.O., N.C.) on page 208 .
Setting 4D: oH Pre-Alarm Time Limit
The output terminal closes when the drive is reducing the speed due to a drive overheat alarm (L8-03 = 4) and the overheat
alarm has not disappeared after 10 frequency reduction operation cycles. Refer to L8-03: Overheat Pre-Alarm Operation
Selection on page 257 for a more detailed description.
Setting 4E: Braking Transistor Fault (rr)
The output closes if the internal braking transistor reaches the overheat level.
Setting 4F: Braking Resistor Overheat (rH)
The output closes when the braking resistor exceeds the overheat level. The braking resistor may overheat due to motor
regeneration or short deceleration time setting.
Setting 50: Waiting to Run (WrUn)
The drive will delay executing a Run command until the time set to b1-11 has expired.
