Control Method Selection

Control
Controls servomotor speed by means of an analog voltage speed
reference. Use in the following instances.
• To control speed
• For position control using the encoder pulse output from the
SERVOPACK to form a position loop in the host controller.
Controls the position of the machine by means of a pulse train
position reference.
Controls the position with the number of input pulses, and con-
trols the speed with the input pulse frequency. Use when posi-
tioning is required.
Controls the servomotor's output torque by means of an analog
voltage torque reference. Use to output the required amount of
torque for operations such as stopping on contact.
Uses the three input signals /P-CON (/SPD-D), /P-CL (/SPD-A),
and /N-CL (/SPD-B) to control the speed as set in advance in the
SERVOPACK. Three operating speeds can be set in the SERVO-
PACK.
When selecting this control, an analog reference is not necessary.
These are switching modes for using the four control methods
given above in combination.
Select the control switching method that best suits the applica-
tion.
The zero clamp function can be used in speed control.
The reference pulse inhibit function can be used in position con-
trol.
