PGF1 PG feedback error (command direction is different from the feedback direction)
When PG feedback control is enabled, check if Pr.10-01 (Encoder PPR) is set to 0.
PGF2 PG feedback loss
Check the PG feedback wiring.
PGF3 PG feedback stall
1. Check the PG feedback wiring.
2. Check if the settings for PI gain and acceleration/deceleration are appropriate (Pr.10-05, Pr.10-06).
PGF4 PG slip error
1. Check the PG feedback wiring.
2. Check if the settings for PI gain and acceleration/deceleration are appropriate (Pr.10-07, Pr.10-08)
