terminal;Open collector output: provide 1 (another 1 can be extended) ;Relay

output: provide 2 (another 1 can be extended) ; Analog output: provide 1

(another 1 can be extended) , 0/4~20mA or 0~10V can be selected.

Protection of speeddeviation

is too large

It can prevent permanent magnet synchronous motor from over speeding.

Over voltage protection

380Vgrade : stop when the voltage of DC bus is more than 800V

Under voltage protection

380Vgrade : stop when the voltage of DC bus is less than 350V

Protect Function

SIN/COS Synchronous

PGCard

UVW Synchronous PG Card

Receive the high speed pulse feedback signal from encoder, to make up a close-loop system with high

precision vector control ; SIN/COS synchronous PG card compatible with SIN/COS synchronous

encoder (the main model is ERN1387 or the encoder witch compatible with its signal) ;

frequency division range : 1—256, frequency division coefficient can be chosen freely by the dial switch.

The standard MODBUS communication protocol inside.

Receive the high speed pulse feedback signal from encoder, to make up a close-loop system with high

precision vector control;

UVW synchronous PG card compatible with UVW synchronous encoder, it needs the motor and the

encoder with the same number of poles;

frequency division range : 1~256, frequency division coefficient can be chosen freely by the dial switch.

CHV180-I/O Extension Card

Offer 4 analog inputs, 1 relay output, 1 analog output, 1 open

collector output, it enhances the input and output capacity.

With RS485 communication interface, customer can detect and

modify the parameters easily.
