12-85

Encoder Stall Level (PGF3)
Control Mode VFPG SVC FOCPG FOCPM Default: 115
Settings 0–120%
0: Disable
 Determines the maximum encoder feedback signal allowed before a fault occurs. (The maximum output
frequency Pr.01-00 = 100%.)

Encoder Stall Detection Time (maximum output frequency Pr.01-00 = 100%)
Control Mode VFPG SVC FOCPG FOCPM Default: 0.1
Settings 0.0–2.0 sec.

Encoder Slip Range (PGF4) (maximum output frequency Pr.01-00 = 100%)
Control Mode VFPG SVC FOCPG FOCPM Default: 50
Settings 0–50%
0: Disable

Encoder Slip Detection Time (maximum output frequency Pr.01-00=100%)
Control Mode VFPG SVC FOCPG FOCPM Default: 0.5
Settings 0.0–10.0 sec.

Encoder Stall and Slip Error Action (maximum output frequency Pr.01-00 =
100%)
Control Mode VFPG SVC FOCPG FOCPM Default: 2
Settings 0: Warn and keep operation
1: Fault and ramp to stop
2: Fault and stop operation
 When the difference of (rotation speed
－
motor frequency) exceeds the Pr.10-07 setting, and the detection
time exceeds Pr.10-08 or the motor frequency exceeds Pr.10-05 setting, the drive starts to count time. If the
detection time exceeds Pr.10-06, the encoder feedback signal error occurs. Refer to Pr.10-09 encoder stall
and slip error action.
