PG feedback loss
Action and Reset
No encoder pulse signal is received by PG card for a certain time during operation
Pr.04-71 Encoder Feedback Signal Fault Detection Time (Default: 1.0 second)
Pr.04-70 (Default: 2)
0: Warn and keep operation
1: Fault and ramp to stop
2: Fault and stop operation
Auto When Pr.04-70=0, PGF2 is a warning will be automatically cleared.
Manual When Pr.04-70=1 or 2, PGF2 is a fault and it must be reset manually.
Resets immediately
If PGF2 is a warning, it will not be recorded.
If PGF2 is a fault, it will be recorded.
Set encoder parameter settings again (Pr.00-20–Pr.00-23)
Check if the wiring is correct.
1. Check if improper wiring or bad connection of the encoder
2. Remove the causes of motor locked.

PG feedback stall
Action and Reset
Pr.04-73 Encoder Stall Level (Default: 115% of Maximum Output Frequency (Pr.03-
50))
Pr.04-74 Encoder Stall Detection Time (Default: 0.10 second)
Pr.04-72 (Default: 2)
0: Warn and keep operation
1: Fault and ramp to stop
2: Fault and stop operation
PGF3 is a warning when Pr.04-72=0. It will be automatically cleared when
Auto the difference between Frequency command and feedback frequency is
smaller than encoder slip range.
Manual PGF3 is a fault when Pr.04-72= 1 or 2. You must reset it manually.
Resets immediately
If PGF3 is a warning, it will not be recorded.
If PGF3 is a fault, it will be recorded.
Verify motor specification and set motor parameter settings again (Pr.00-10–Pr.00-16)
Set ASR-related parameters again.
Adjust acceleration /deceleration time (Pr.00-71–Pr.00-78)
Properly increase Pr.04-73 and Pr.04-74 settings
Chapter 9 Warning and Fault CodesEB3000
When using control mode with PG feedback
function and a speed command is given, drive
detects that no encoder pulse signal is
received by PG card for a certain time, and
the time error occurred exceeds Pr.04-71
detection time.
Corrective Actions
In PG mode, when motor frequency exceeds
Pr.04-73 (Encoder Stall Level) and starts to
count the time, and the time error occurred
exceeds Pr.04-74 (Encoder Stall Detection
Time), PGF3 occurs.
Corrective Actions
9-33
