S1 series standard inverter
Terminal
name
Voltage range: 12–24V
1. Contact capacity: 50mA / 30V
Y1
2. Output frequency range: 0 – 1kHz
+24V-H1
1. Safe torque off (STO) redundant input, connect to external NC contact, STO acts
when the contact opens, and the inverter stops output
+24V-H2
2. Safety input signal wires use shielded wire whose length is within 25m
+ 24V The inverter provides user power; the maximum output current is 200mA
COM
Common port of + 24V
10V reference power supply
+ 10V
Max. Output current: 50mA
1. Input range: AI2 voltage and current can be chosen: 0 – 10V / 0 – 20mA; AI3: -10V
AI2
– + 10V
2. Input impedance: voltage input: 20kΩ; current input: 500Ω
3. Voltage or current input can be set by toggle switch
AI3
4. Resolution: the minimum AI2 / AI3 is 10mV / 20mV when 10V corresponds to
50Hz
GND Analog reference ground
1. Output range: 0 – 10V voltage or 0 – 20mA current
AO1 2. Voltage or current output is set by toggle switch
3. Error ± 1%, 25 ° C
RO1A
1. Contact capacity: 3A / AC250V, 1A / DC30V
RO1B
2. Please note that it should not be used as high frequency switch output
