1.5 Control Modes of Servo Drive
The Delta Servo provides six single and five dual modes of operation.
Their operation and description is listed in the following table.
Mode Code Description
External Position Control P
External Position control mode for the servo motor
is achieved via an external pulse command.
Speed Control S
(External / Internal) Speed control mode for the
servo motor can be achieved via parameters set
within the controller or from an external analog -10
~ +10 V
DC
command. Control of the internal speed
mode is via the Digital Inputs (DI). (A maximum of
three speeds can be stored internally).
Internal Speed Control Sz
Internal Speed control mode for the servo motor is
only achieved via parameters set within the
controller. Control of the internal speed mode is via
the Digital Inputs (DI). (A maximum of three speeds
can be stored internally).
Torque Control T
(External / Internal) Torque control mode for the
servo motor can be achieved via parameters set
within the controller or from an external analog -10
~ +10 V
DC
command. Control of the internal torque
mode is via the Digital Inputs (DI). (A maximum of
three torque levels can be stored internally).
Single
Mode
Internal Torque Control
Tz Internal Torque control mode for the servo motor is
only achieved via parameters set within the
controller. Control of the internal torque mode is
via the Digital Inputs (DI). (A maximum of three
torque levels can be stored internally).
S-P Either S or P control mode can be selected via the
Digital Inputs (DI)
T-P Either T or P control mode can be selected via the
Digital Inputs (DI)
Dual Mode
S-T Either S or T control mode can be selected via the
Digital Inputs (DI)
The above control modes can be accessed and changed via parameter P1-01. Enter the new
control mode via P1-01 then switch the main power to the servo drive OFF then ON. The new
control mode will only be valid after the drives main power is switched OFF then ON. Please
see safety precautions on page iii (switching drive off/on multiple times).
