AO1
1. Output range: 0
–10V voltage or 0–20mA current
2. Voltage or current output is set by toggle switch SW2;
3. 25°C, when input above 5V or 10mA, the error is ±0.5%.
RO1A
RO1 relay output; RO1A is NO, RO1B is NC, RO1C is common port
Contact capacity: 3A/AC250V, 1A/DC30V
RO1B
RO1C
RO2A
RO2 relay output; RO2A is NO, RO2B is NC, RO2C is common port
Contact capacity: 3A/AC250V, 1A/DC30V
RO2B
RO2C
HDO
1. Switch capacity: 50mA/30V;
2. Range of output frequency: 0
–50kHz
3. Duty ratio: 50%
COM
Common port of +24V
CME
Common port of open collector output; short connected to COM by default
Y1
1. Switch capacity: 50mA/30V;
2. Range of output frequency: 0
–1kHz
485+
485 communication port, 485 differential signal port and standard 485
communication interface should use twisted shielded pair; the 120
Ω terminal
matching resistor of 485 communication is connected by toggle switch SW3.
485-
PE
Grounding terminal
PW
Provide input digital working power from external to internal;
Voltage range: 12
–30V
24V
The VFD provides user power; the max. output current is 200mA
S1
Digital input 1
1.
Internal impedance: 3.3kΩ
2. Accept 12
–30V voltage input
3. This terminal is bi-directional input terminal and supports
NPN/PNP connection modes
4. Max. input frequency: 1kHz
5. All are programmable digital input terminals, users can set the
terminal function via function codes
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
speed-measurement function
HDIB
+24V
—H1
STO input 1
1. Safe torque off (STO) redundant input, connect to external NC
contact, STO acts when the contact opens, and the VFD stops
output;
2. Safety input signal wires use shielded wire whose length is
within 25m;
3. H1 and H2 terminals are short connected to +24V by default; it
is required to remove the jumper on the terminal before using
STO function.
