ST2 9
When ST2-SG are shorted in the automatic operation mode,
positioning is executed once in the reverse rotation direction on the
basis of the position data set to the point table.
In jog operation mode, the servo motor rotates in the reverse
rotation direction while ST2-SG are shorted.
Reverse rotation denotes the direction in which the address is
decremented.
MDO 7 Short MDO-SG to choose the automatic operation mode, or open
them to choose the manual operation mode.
DI0 5 The following table lists the point table numbers which may be
chosen by the combinations of DI0 and DI1:
DI1 14
(Note) Input signals
Note: 0: DI1/DI0-SG open
CPO 4 CPO-SG are connected when the remaining command distance falls
within the parameter-set rough match output range. This signal is
not output while the base circuit is off.
Switching the servo-on connects CPO-SG.
INP 6 INP-SG are connected when the number of droop pulses is in the
preset in-position range. The in-position range can be changed using
parameter No. 6.
When the in-position range is increased, INP-SG may be kept
connected during low-speed rotation.
Switching the servo-on connects INP-SG.
ALM 18 ALM-SG are disconnected when power is switched off or the
protective circuit is activated to shut off the base circuit. Without
alarm, ALM-SG are connected within 1 after power on.
RD 19 RD-SG are connected when the servo is switched on and the servo
amplifier is ready to operate.
VC 2 10 to 10V is applied to across VC-LG to limit the servo motor
speed. Apply
200[%].
TLA 12 To use this signal, make external torque limit selection (TL) usable
with the Servo Configuration software.
Then the analog torque limit (TLA) is valid, torque is limited in the
full servo motor output torque range. Apply 0 to 10VDC across TLA-
LG. Connect the positive terminal of the power supply to TLA.
Maximum torque is generated at 10V. (Refer to (5) in Section 3.4.1.)
Resolution: 10bit
SD Plate Connect the external conductor of the shield cable.
