1.5 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.
Mode
Code
Description
External Position Control
Pt
Position control for the servo motor is achieved via an
external pulse command.
Internal Position Control
Pr
Position control for the servo motor is achieved via by 8
commands stored within the servo controller. Execution of
the 8 positions is via Digital Input (DI) signals.
Speed Control
S
Speed control for the servo motor can be achieved via
parameters set within the controller or from an external
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).
Internal Speed Control
Sz
Speed control for the servo motor is only achieved via
parameters set within the controller. Control of the internal
speed parameters is via the Digital Inputs (DI). (A maximum
of three speeds can be stored internally).
Torque Control
T
Torque control for the servo motor can be achieved via
parameters set within the controller or from an external
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).
Single
Mode
Internal Torque Control
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)
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 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).
