b5-36: PID Feedback High Detection Level
Determines the level at which a PID feedback alarm occurs. The alarm is triggered when PID feedback exceeds the level specified in b5-36 for longer
than the time designated in b5-37. When the alarm is triggered, “FbH” will appear on the operator and the drive will continue running. If the drive is set
to trigger a fault, then a fault will be output through one of the multi-function output terminals and a stop command will be issued.
No. Parameter Name Setting Range Default
b5-36 PID Feedback High Detection Level 0 to 100 100
• Set as a percentage of the maximum frequency output (E1-04).
n
b5-37: PID Feedback High Detection Time
Determines the time in seconds for the PID feedback level to trigger PID Feedback High detection.
No. Parameter Name Setting Range Default
b5-37 PID Feedback High Detection Time 0.0 to 25.5 1.0
n
b5-38: PID Setpoint / User Display
Determines whether or not the PID value is shown when the maximum output frequency is reached. Enabled when b5-20 = 3.
No. Parameter Name Setting Range Default
b5-38 PID Setpoint / User Display 0 to 60000 Determined by b5-20
n
b5-39: PID Setpoint and Display Digits
Determines the number of digits for setting and displaying the PID setpoint. Enabled when b5-20 = 3.

b6-03/b6-04: Dwell Reference/Time at Stop
The reference hold or Dwell function is used to temporarily hold the output frequency at a set reference, for a set time, and then continue to ramp up. This
function can be used when driving a permanent magnet motor, or a motor with a heavy starting load. This pause in acceleration allows the magnets in a
permanent magnet motor to synchronize with the stator field of the motor, thus reducing traditionally high starting current.
Note: Using the Dwell function requires that the stopping method for the drive be set to “Ramp to Stop” (b1-03 = 0).
No. Parameter Name Setting Range Default
b6-01 Dwell Reference at Start 0.0 to 400.0 0.0 Hz
b6-02 Dwell Time at Start 0.0 to 10.0 0.0 s
b6-03 Dwell Reference at Stop 0.0 to 400.0 0.0 Hz
b6-04 Dwell Time at Stop 0.0 to 10.0 0.0 s
