Remark of drive interface is as follows:
Signal
Definition
Input/Output
Remark
A+, A-
Feedback signal of
encoder phase A
Input, differential
signal transmission
mode
It is used to receive the
differential output of
encoder phase A signal
from driver frequency
divider (equal to RS422).
B+, B-
Feedback signal of
encoder phase B
Input, differential
signal transmission
mode
It is used to receive the
differential output of
encoder phase B signal
from driver frequency
divider (equal to RS422).
C+, C-
Feedback signal of
encoder phase C
Input, differential
signal transmission
mode
It is used to receive the
differential output of
encoder phase C signal
from driver frequency
divider (equal to RS422).
ALM
Drive alarm signal
Input
When the drive detects
failure, this output
(transistor) switch will
be closed or
disconnected.
SON
Servo ON signal
Output
It is used to turn on
(power on) and turn off
(power off) servo motor.
When it is connected to
COM, dynamic brake will
be released and the drive
is allowed to work (servo
enabled).
CLR
Drive alarm clear
signal
Output
It is used to remove
alarms/warnings.
PUL+, PUL-
Pulse output
Output, differential
signal transmission
mode
-
DIR+, DIR-
Direction output
Output, differential
signal transmission
mode
-
INTSPD2
Internal command
speed option 2
Output
-
ZSP
Speed zero clamp
detection signal
Output
In speed zero clamp
detection status, the
output transistor is
turned on.
