No.
L4-04 Speed Agreement Detection Width (+/-)
Note: During acceleration, the terminal set for Frequency Detection 4 will close if the output frequency is greater than the frequency detection level (L4-03) and the frequency
detection width (L4-04). During deceleration, the terminal set for Frequency Detection 4 will close as long as the output frequency is less than the frequency detection level
(L4-03). The output for Frequency Detection 4 is direction sensitive according to the direction programmed in L4-03.
Setting 1A: During Reverse
The During Reverse digital output will close and remain closed whenever the drive is turning the motor in the reverse direction.
Setting 1B: Baseblock, N.C.
Output opens only when the drive is in a baseblocked state.
Setting 1C: Motor 2 Selected
Output closes whenever a multi-function input programmed for motor 2 selection (H1-0x = 16) is closed.
Setting 1E: Restart Enabled
Depending on the setting of parameter L5-01, the drive may be configured to automatically attempt to restart itself after certain faults. The Restart Enabled
output will be closed once the restarts begin and will remain closed until a successful restart is accomplished or the number of Auto Restart attempts as
specified by L5-01 is reached.
No.
L5-01 Number of Auto Restart Attempts
Setting 1F: Overload Alarm oL1
The oL1 fault function is designed to protect the motor. It estimates the motor's winding temperature based on the output current, output frequency, and
time. An Overload Alarm oL1 digital output will close whenever 90% of the programmed oL1 time is exceeded.
Status
Open
Closed
Setting 20: OH Prealarm
Output closes whenever the heatsink temperature reaches the level specified by parameter L8-02. Parameter L8-03 will determine how the drive responds
when it reaches the OH Prealarm level, in addition to closing the configured digital output.
Status
Open
Closed
No.
L8-02 Overheat Alarm Level
Setting 22: Mechanical Weakening Detection
Output closes when mechanical weakening is detected.
Setting 30: During Torque Limit (Current Limit)
When the torque reference reaches the torque limit set in L7-01 to L7-04, the output programmed for During Torque Limit closes. This setting is only
valid when using Open Loop Vector Control (A1-02 = 2).
No. Parameter Name
L7-01 Forward Torque Limit
L7-02 Reverse Torque Limit
L7-03 Forward Regenerative Torque Limit
L7-04 Reverse Regenerative Torque Limit
Setting 37: During Frequency Output
Output closes whenever the Run command is provided and the drive is outputting frequency. This does not include baseblock, DC Injection, Short Circuit
Braking, and Initial Excitation.
