Control Modes of Servo Drive

The Delta Servo can be programmed to provide six single and five dual modes of operation.
Their operation and description is listed in the following table.
External Position Control
Internal Position Control
Single
Mode
Internal Speed Control
Internal Torque Control
Dual Mode
The above control modes can be accessed and changed via by parameter P1-01. If the control mode is
changed, switch the drive off and on after the new control mode has been entered. The new control mode
will only be valid after drive off/on action. Please see safety precautions on page iii (switching drive off/on
multiple times).

Position control for the servo motor is achieved via an
Pt
external pulse command.
Position control for the servo motor is achieved via by 8
Pr commands stored within the servo controller. Execution of
the 8 positions is via Digital Input (DI) signals.
Speed control for the servo motor can be achieved via
parameters set within the controller or from an external
S analog -10 ~ +10 Vdc command. Control of the internal
speed parameters is via the Digital Inputs (DI). (A maximum
of three speeds can be stored internally).
Speed control for the servo motor is only achieved via
parameters set within the controller. Control of the internal
Sz
speed parameters is via the Digital Inputs (DI). (A maximum
of three speeds can be stored internally).
Torque control for the servo motor can be achieved via
parameters set within the controller or from an external
T analog -10 ~ +10 Vdc command. Control of the internal
torque parameters is via the Digital Inputs (DI). (A
maximum of three torque levels can be stored internally).
Tz Torque control for the servo motor is only achieved via
parameters set within the controller. Control of the internal
torque parameters is via the Digital Inputs (DI). (A
maximum of three torque levels can be stored internally).
Pt-S Either Pt or S control mode can be selected via the Digital
Inputs (DI)
Pt-T Either Pt or T control mode can be selected via the Digital
Inputs (DI)
Pr-S Either Pr or S control mode can be selected via the Digital
Inputs (DI)
Pr-T Either Pr or T control mode can be selected via the Digital
Inputs (DI)
S-T Either S or T control mode can be selected via the Digital
Inputs (DI)
