HD2 Series Inverter Installation Guidelines
-27-
Whether the output type is voltage or current can be set through DIP switch SW2
Error: ±0.5% at 25°C when input is above 5V/10mA
RO1 relay output; RO1A is NO, RO1B is NC, RO1C is common
Contact capacity: 3A/AC250V, 1A/DC30V
RO2 relay output; RO2A is NO, RO2B is NC, RO2C is common
Contact capacity: 3A/AC250V, 1A/DC30V
Switch capacity: 50mA/30V
Range of output frequency: 0–50kHz
Duty ratio: 50%
Common port of open collector output; short connected to COM by default
Switch capacity:50mA/30V; Range of output frequency: 0–1kHz
RS485 communication/differential signal port. The standard 485 communication
interface should use twisted shielded pair; the 120ohm terminal matching resistor of
RS485 communication can be connected through DIP switch SW3.
Provides input digital working power from external to internal
Voltage range: 12–30V
User power provided by the inverter. Max. output current: 200mA
Internal impedance: 3.3kΩ
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.
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
Safe torque off (STO) redundant inputs, connected to external
NC contacts. When the contacts open, STO acts and inverter
output stops.
Safety input signal cable: shielded, with length within 25m
H1 and H2 terminals are short connected to +24V by default.
Remove the short-contact tag on the terminal before using STO
function.
