6. SERVO MOTOR DRIVING
6 - 84
(c) Operation
Switching on "Controlword bit 4 (Rotation start)" starts rotation to a direction specified with
"Controlword bit 5 (Direction)", and switching off "Controlword bit 4 (Rotation start)" executes a
positioning to the closest station position where the servo motor can decelerate to a stop. Note that
the speed may not reach the specified speed because the shaft stops with the set time constant,
depending on the setting value of deceleration time constant.
Item
Object to be used
Setting
Rotation direction selection
Controlword
Set the rotation direction in "Controlword bit 5 (Direction)".
The setting is shown as follows:
Off: Station No. decreasing direction
On: Station No. increasing direction
Start/stop Controlword
Set start/stop in "Controlword bit 4 (Rotation start)". The
setting is shown as follows:
On: start
Off: stop at a station which is the closest and possible to
decelerate to a stop
