CHAPTER 16. SIGNAL TIMING
16-1. POWER ON SEQUENCE
The servo amplifier can accept the servo-on
signal about 2sec. after the main circuit
power supply is switched on.
Also, the external reset input makes the
same effect as power-on sequence.
The minimum pulse width of reset input is
50msec and the maximum of that is 0.2sec.
When the reset input is switched on, the
base drive circuit will switch off immediately.
16-2. SERVO ON / OFF SEQUENCE
(In case of non-brake)
The
brake
is
not
used
when
Setup-36
"O5/BK" set in 0.
The base drive circuit will switch on/off after
the servo-on signal is switched on/off for
longer than 20msec.
16-3. BRAKE ON / OFF SEQUENCE
The brake is used when Setup-36 "O5/BK" set in 1.
Set a time delay between electromagnetic brake signal output on and servo on in
Svpar-10 "BRKTM"
.
The unit is msec. The mechanical movement is occurred due to free-run when the setting value is too
higher than the optimal value. But, be sure that the motor shaft is damaged due to locking when the
setting value is too lower than the optimal value.
The safety speed of electromagnetic brake action is set in 300 rpm.
The timing of electromagnetic brake signal off is delayed until the speed reaches at 300 rpm, when
the servo motor is stopped freely at a running.
