3.3.2.3 Step 3
Trial run for FOCPG feedback control
Selection for speed feedback card
Please refer to Appendix B PG card for selection. Delta provides 3 PG cards, including EMV-
PG01X, EMV-PG01O and EMV-PG01L, for your selection.
Encoder pulse
Pr.10-00
Encoder Pulse
1~20000
Selection for encoder input type
Pr.10-01
Encoder Input Type
Setting
0: Disable
1: Phase A leads in a forward run command and phase B
leads in a reverse run command
2: Phase B leads in a forward run command and phase A
leads in a reverse run command
3: Phase A is a pulse input and phase B is a direction
input. (low input=reverse direction, high input=forward
direction)
4: Phase A is a pulse input and phase B is a direction
input. (low input=forward direction, high input=reverse
direction)
5: Single-phase input
Set it to FOCPG mode
Pr.00-10
Control Method
0: V/f Control
1: V/f C Encoder (VFPG)
2: Sensorless vector control (SVC)
3: FOC vector c Encoder (FOCPG)
4: Torque c Encoder (TQCPG)
Check if the PG feedback card is normal
1. check if the actual output frequency reaches the frequency command
2. When the PG feedback card is abnormal, the fault code.
Check if Pr.10-01 is set to 0
Check if the wiring of the feedback card is correct
Check if the wiring of the feedback card, PI gain parameter
is correct or adjust decel./accel. time
Check if the wiring of the feedback card, PI gain parameter
is correct or adjust decel./accel. time
After the fault is cleared, please trial run again.
Check if the output current is normal
When changing frequency command, check if the output current is increased or decreased
abnormally. If it is abnormal, please check if Pr.10-00 and Pr.10-27~Pr.10-28 are correct.
Changing the rotation direction of the motor
Adjust the rotation direction of the motor to ensure that it can run in all the rotation directions.
Increase the frequency command
Check if the output current/frequency and motor actual speed(it can set Pr.00-04=7 during
operation) is normal in different commands.
Finish trial run
If the results of trial run are normal, the trial run in FOCPG mode is completed.
