Chapter 6 Control Modes of Operation
6.1 Control Modes of Operation
The Delta ASDA-B2 series 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
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 steps of changing mode:
(1)
Switching the servo drive to Servo Off status. Turning SON signal of Digit input to be off
can complete this action.
(2)
Using parameter P1-01. (Refer to chapter 7).
(3)
After the setting is completed, cut the power off and restart the drive again.
The following sections describe the operation of each control mode, including control
structure, command source and loop gain adjustment, etc.
