Figure 3.5 Power supply, motor and motor limit port
In genal, motor limit switch keep close. The limit switch is keep close in THC.
Therefore, the parameter L06, L07 should be set as 1. If user make switch keep open,
the parameter L06, L07 should be set as 0.
The socket which have 7 pin description:

Signal Content
2.1 UP_LIMIT UP_LIMIT input of dc motor. When contactor keep
close and limit switch do not work, pin2.1 and
pin2.3 is connected. When motor have collided limit
switch, limit switch start work, pin2.1and pin2.3 is
disconnected.
2.2 DOWN_LIMIT DOWN_LIMIT input of dc motor. When contactor
keep close and limit switch do not work, pin2.1 and
pin2.3 is connected. When motor have collided limit
switch, limit switch start work, pin3 and pin5 is
disconnected.

2.4，2.5 MOTOR PORT
（MOTOR1，
MOTOR2）
DC motor driver output, it connect positive and
negative electrode of 24V dc motor, the biggest
motor power is 100W. If user want to change DC
motor direction of rotation, it will be came true by
