The synchronous motor drive PG interface card uses a 5 V power supply.
[PGP] pin: +5 V ±5%, 250 mA, [PGM] pin: Common, Includes an overcurrent protection function.
Internal photocoupler insulation
(connected to [PGM] and [CM] on the inverter's control Pt board; isolated from [M])
PG power supply
The inverter's PG power supply (+15 V, +12 V) can
also be used to power the motor encoder. Connect
after checking the motor encoder's specifications.

Photocoupler insulation
Broken wire
detection function Yes No
Connections
Supply the 5 V power supply from [PGP] and
[PGM]. Since a balanced circuit is used, it is
necessary to use twisted-pair shielded cable for
wiring. Built-in 5 V pull-up; sink current: approx. 11
mA/circuit
Maximum input
pulse frequency 100 kHz; duty: 50 ±10%
Allowable wiring
length
Approx. 50 m
Shorter wiring lengths are required when there is a
high voltage drop. 10 m or less
Keep wiring runs as short as possible to avoid the
effects of noise. Be sure to connect a zero-phase
ferrite ring.
Power supply
24V
Supplied from the inverter's printed circuit board. Connect the power supply harness to CN24 or CN25 on the
inverter.

PG interface functionality
When the PMPG option is installed and function code P01 (M1 control method selection), A01
(M2 control method selection), or A101 (M3 control method selection) = 3, the built-in PG
interface is disabled, and the PMPG option takes priority.
Broken wire detection function Yes
Frequency division output No
Magnetic pole position detection
function
Configured with function code o09 (ABS signal input definition).
o09 = 1: 3-bit detection; [F0] [F1] [F2] : U-/V-/W-phase detection
o09 = 2: 4-bit detection; [F0] [F1] [F2] [F3]: Gray code detection
