Input /Output
Description
C+, C-
Feedback signal of
encoder phase C
Input, differential signal
transmission mode
Used for detecting encoder origin
ALM
Driver alarm signal
Input
When breakdown occurs in driver,
this output (transistor) switch will be
closed or disconnected.
SON
Servo ON signal
Output
This signal is used for opening
(power on) and closing (power off)
servo motor. When this signal is
connected to COM-, dynamic brake
will be released and thus the driver is
allowed to work (servo enabled).
PUL+,
PUL-
Pulse output
Output, differential signal
transmission mode
DIR+,
DIR-
Direction output
Output, differential signal
transmission mode
+24V,
GND
DC 24V power
Output
Connected to driver
CAUTION
SON signal will be effective at 2 seconds after power on. Don’t try to drive the motor through the external servo
ON or servo OFF drive signal at any time, since the software will control the enabling state of the servo motor.
2.2.4 Handwheel Interface
NK200 is capable of externally connecting with manual pulse generator, with DB15 core dual-in-line
holes joint. Its pin definition is as shown in Fig. 2-11.
