Pr. 122
PID Frequency Output Command limit
Factory Setting: 00
Settings 00 to 110 %
 This parameter sets a limit of the PID Command frequency. If this parameter is set to
20%, then the maximum output frequency for the PID operation will be (20% x Pr.01-00).
Pr. 123
Feedback Signal Detection Time
Factory Setting: 60.0
Settings 0.1 to 3600 sec Unit: 0.1sec
0.0 disable
 This parameter defines the detection time for the loss of a feedback analog signal. The
drive will follow the operating procedure programmed in Pr.124 if the feedback signal is
lost for more than the time set in Pr.123.
Pr. 124
Feedback Signal Fault Treatment
Factory Setting: 00
Settings 00 Warning and RAMP to stop
01 Warning and COAST to stop
 This parameter selects the operation of the drive upon a loss of the PID feedback signal.
Pr. 125
Source of PID Set point
Factory Setting: 0.00
Settings 0.00 to 400.0Hz
 This parameter is used in conjunction with Pr.115 (04) to input a set point in Hz.
Pr. 126
PID Offset Level
Factory Setting: 10.0
Settings 1.0 to 50.0 %
 This parameter is used to set the offset between set point and feedback.
Pr. 127
Detection Time of PID Offset
Factory Setting: 5.0
Settings 0.1 to 300.0 sec
 This parameter is used to set the detection time of PID offset.
Pr. 128
