AVR
Output voltage remains unchanged basically and input
voltage varies when AVR is active
Automatic
Current Limit
Automatically limit output current to avoid frequently
overcurrent trip.
DC Brake
Brake frequency: 0.01 - Maximum frequency, brake time: 0 -
30S
Brake current: 0% - 100% rated current

Control Power
Supply
24V/200mA
Numeric Input
Terminal
7 (standard X1 - X7) + 4 (expansion card X8 - X11) numeric
multi-functional input terminals:
X7 can be selected as high-speed impulse input terminal
(
F02.06=35/38/40
);
X1 - X6 and X8 - X11 (10 in total) can be used as common
digital input terminals.
Analog Input
Terminal
3 (standard
AI1
-
AI3
) + 1 (expansion card
AI4
) analog
input terminals:
1 (AI1) voltage source 0 - 10 input;
2 (AI2/AI3) voltage source 0 - 10V inputs or current
source 0 - 20mA input;
1 (AI4) voltage source -10V - 10V input
Numeric Output
Terminal
2 (standard
Y1/Y2
) + 1 (expansion card Y3) OC
multi-functional outputs and 2 (
R1: EA/EB/EC and R2:
RA/RB/RC
) relay multi-functional outputs.
Maximum output current of OC: 50mA; relay contact
capacity: 250VAC/3A or 30VDC/1A. When the relay works,
EA-EC and RA-RC are on, but EB-EC and RB-RC are off.
Analog Output
Terminal
M1 is with output 0 - 10V only.
M2 is with output 0 - 10V or 0 – 20 mA.
