3.3.4. CN1 pin function description
There are 50 pins in CN1. Every pin and its default function are described as below. Some pin
functions are varied depending on the control mode.
There is a +15V between VCC and LG. It could be
used as an analog power of TC, TLA, VC and VLA.
Speed analog
command/
limit
Apply -10V~+10V between VC and LG in speed
mode, the motor will run the PC12 speed
proportionally at ±10V.
Apply -10V~+10V between VC and LG in torque
mode, the motor will run the PC12 speed
proportionally at ±10V.
CN1_3
CN1_4
CN1_10
CN1_11
CN1_28
CN1_29
CN1_31
The common ground of VC, VLA, TC, TLA, OP,
MOM1, MON2. Each pin inside the drive is
connected together.
Torque analog
command/limit
Apply -10V~+10V between TC and LG, the motor
torque generated will be the PC13 value
proportionally at ±10V.
As TLA is valid, motor generated torque would be
limited according to proportion of rated torque to
applied voltage.
The applied voltage range on TLA-LG is 0 ~ +10V.
Forward/rever
se rotation
pulse
Open collector type: (Max. frequency 200Kpps)
Signals on PP-SG means “forward command”.
Signals on NP-SG means “reverse command”.
Differential line driver (Max. frequency 500Kpps)
Signals on PP-PG means “forward command”.
Signals on NP-NG means “reverse command”.
When pulse signals applied in open collector type;
this pin provides 24V and SG is the ground.
