Chapter 5 Debugging Process; Confirm The Wiring Correct Connected And Firm; Self-Learning Parameters Setting - V&T V5 Series User Manual

5.1Confirm the wiring correct connected and firm

Before wiring, make sure that everything is in the off state;
◆
Main circuit: Input power connect R / S / T, motor connect U / V / W;
◆
If built-in braking unit, braking resistor connect to B1 and B2; if external braking unit connect to +2 and
-, braking
resistor connect to the brake unit;
Control loop: Confirm forward, reverse, speed, fault reset, safety interlock protection, fault output,
◆
brakes and other wiring correct;
wiring is completed, check the cables to be reliable, no virtual connection or loose terminals
◆
phenomenon.
X terminal supports AC input wiring mode (voltage range: AC24V~48V, if you need X terminal input
◆
AC36V or AC48V, please add -67 after ordering model)
Note: Be sure to remove the shorting tab between +24V and PLC.

5.2 Self-learning parameters setting

◆ Please disconnected the motor load when auto tuning, when auto tuning the motor rotates, we must
pay attention to safety;
◆ After finished auto tuning please record all the parameter of motors. If later restore parameters no
need to auto tuning just input directly;
◆ Confirm forward is upward direction, reverse is downward direction. If the opposite direction, please
swap any two motor wires.
