Delta VFD-VE - Feedback Signal Detection Time; Feedback Fault Treatment; Sleep Frequency; Wake-Up Frequency, Sleep Time

Chapter 4 Parameters
4-138
08-08  Feedback Signal Detection Time Unit: 0.1
Control
mode
VF VFPG SVC FOCPG
Factory Setting: 0.0
Settings 0.0 to 3600.0 sec
 This parameter is only valid when the feedback signal is ACI.
 This parameter defines the time during which the PID feedback must be abnormal
before a warning is given. It also can be modified according to the system feedback
signal time.
 If this parameter is set to 0.0, the system would not detect any abnormality signal.
08-09 Feedback Fault Treatment
Control
mode
VF VFPG SVC FOCPG
Factory Setting: 0
Settings 0 Warn and keep operating
1 Warn and RAMP to stop
2 Warn and COAST to stop
3 Warn and keep at last frequency
 This parameter is only valid when the feedback signal is ACI.
 AC motor drive acts when the feedback signals (analog PID feedback or PG (encoder)
feedback) are abnormal.

 These parameters determine sleep functions of the AC drive. If the command frequency
falls below the sleep frequency, for the specified time in Pr. 08-12, then the drive will
