Instruction
3. Whether the input is voltage or current is set through P05.50;
4. Resolution ratio: When 10V corresponds to 50Hz, the min. resolution ratio is
5mV;
5. Deviation: ±0.5% at 25°C, when input is above 5V/10mA.
GND
+10.5V reference zero potential
AO1
1. Output range: 0–10V or 0–20mA
2. Whether the output is voltage or current is set through the switch SW2
3. Deviation: ±0.5% at 25°C, when input is above 5V/10mA.
RO1A
RO1 relay output; RO1A is NO, RO1B is NC, RO1C is common terminal
Contact capacity: 3A/AC250V, 1A/DC30V
RO1B
RO1C
RO2A

RO2B
RO2C
HDO
1. Switch capacity: 200mA/30V
2. Range of output frequency: 0–50kHz
3. Duty ratio: 50%
COM
Common terminal of +24V
CME
Common terminal of open collector output; short connected to COM by default
Y1
Switch capacity: 200mA/30V
Range of output frequency: 0–1kHz
485+
RS485 communication port, RS485 differential signal port and standard RS485
communication port must use twisted shielded pair; the 120ohm terminal matching
resistor of RS485 communication is connected by the switch SW3.
485-
PE
Grounding terminal
PW
Use to provide input digital working power from the external to the internal.
Voltage range: 12–30V
+24V
User power provided by the VFD, maximum output current 200mA.
COM
Common terminal of +24V
S1
Digital input 1
1. Internal impedance: 3.3kΩ
2. Accept 12–30V voltage input
3. Bi-directional input terminal, supporting NPN/PNP connection
modes
4. Max. input frequency: 1kHz
5. All are programmable digital input terminals, the functions of
which be set through function codes
S2
Digital input 2
S3
Digital input 3
S4
Digital input 4
HDIA
Besides S1–S4 functions, the terminals can also act as high frequency pulse input
channels
Max. input frequency: 50kHz;
Duty ratio: 30%–70%;
Supporting quadrature encoder input; equipped with speed-measurement function
HDIB
+24V—H1
STO input 1
1. Safe torque off (STO) redundant input, connected to the
external NC contact. When the contact opens, STO acts and the
VFD stops output;
2. Safety input signal wires use shielded wires whose length is
within 25m;
3. The H1 and H2 terminals are short connected to +24V by
default. Remove the short connectors from the terminals before
using STO function.
