RO1C
RO2A
RO2 relay output; RO2A is NO, RO2B is NC, RO2C is common
RO2B
Contact capacity: 3A/AC250V, 1A/DC30V
RO2C
 Switch capacity: 50mA/30V
 Range of output frequency: 0–50kHz
HDO
 Duty ratio: 50%
CME Common port of open collector output; short connected to COM by default
Y1 Switch capacity:50mA/30V; Range of output frequency: 0–1kHz
485+ RS485 communication/differential signal port. The standard 485 communication
interface should use twisted shielded pair; the 120ohm terminal matching resistor of
485-
RS485 communication can be connected through DIP switch SW3.
PE Grounding terminal
Provides input digital working power from external to internal
PW
Voltage range: 12–30V
24V User power provided by the VFD. Max. output current: 200mA
COM Common terminal of +24V
Digital input 1  Internal impedance: 3.3kΩ
S1
S2 Digital input 2
S3 Digital input 3
S4 Digital input 4
HDIA Besides S1–S4 functions, it can also act as high frequency pulse input channel
Max. input frequency: 50kHz. Duty ratio: 30%–70%
Supports the input of a quadrature encoder with 24V power supply; equipped with
HDIB
speed-measurement function
+24V—H1 STO input 1
+24V—H2 STO input 2
Description
 Accept 12–30V voltage input
 Bi-directional input terminals, supporting NPN/PNP modes
 Max. input frequency: 1kHz
 All are programmable digital input terminals. You can set the
terminal function via function codes.
 Safe torque off (STO) redundant inputs, connected to external
NC contacts. When the contacts open, STO acts and VFD output
stops.
 Safety input signal cable: shielded, with length within 25m
 H1 and H2 terminals are short connected to +24V by default.
Remove the jumper on the terminal before using STO function.
