F1-19: dv4 Detection Selection (CLV/PM)
■
Sets the number of pulses necessary to trigger a dv4 fault when there is a motor speed deviation opposite to the frequency
reference. Setting F1-19 to 0 disables dv4 detection.
No.
F1-19
Note: A common cause for a dv4 fault is the incorrect setting of E5-11. Make sure the correct encoder offset is set to E5-11.
■ F1-20: PG Option Card Disconnect Detection 1
Sets whether the drive detects a fault when a speed feedback card is disconnected.
No.
F1-20
Setting 0: Disabled
Setting 1: Enabled
■ F1-29: dEv Detection Condition Selection
Selects when dEv error detection is active.
No.
F1-29
Setting 0: After speed reference, SFS output and motor speed have matched once.
Setting 1: After speed reference, SFS output have matched once.
Setting 2: Always during Run.

■ F1-50: Encoder Selection
Note: Available in drive software PRG: 7016 or later.
Sets up the type of encoder connected to a PG-F3 option card.
No.
F1-50
Setting 0: EnDat 2.1/01, 2.2/01 Serial Communications operation + Sin/Cos
Setting 1: EnDat 2.2/22 Serial Communications operation
Setting 2: HIPERFACE
The use of EnDat2.2/22 encoders requires a PG-F3 option with software version 0102 or later.
The use of HIPERFACE encoders requires a PG-F3 option with software version 0104 or later.
To identify the PG-F3 software version refer to the PG-F3 labeling in the field designated "C/N" (S + four digit number).
