3.8 Principles of input and output interfaces
3.8.1 EN, MODE, INTH, CW, and CCW Switch Input Interface
EN, MODE, INTH, CW, and CCW Switch Input Interface
1.DC 12V-24V
2. current < 20mA
3. Please note the
reversed
current
polarity will cause
servo drive to fail
to work properly
4. Inductive must
be connect with
fly-wheel diode in
parallel
connection at the
two end of load
Switch Input Interface
3.8.2 SRDY, ALM, BRAKE, COIN, and OZ Switch Output Interface
SRDY, ALM, BRAKE, COIN, and OZ Switch Output Interface
1. OZ, SRDY, COIN,
and
ALM
signal
maximum current is
20mA;
BRAKE
signal
maximum
current is 50mA;
2. Output is open
collector form.
3. please note the
reversed
current
polarity
will
lead
servo drive to be
damaged.
