6.3. Torque Control Mode Opeation
6.3.1. RS-232C Communication Command Operation
6.3. Velocity Control Mode Operation
l
Positioning with velocity control mode is not available to the B3 and 23 type Driver Units.
l
The parameter SL sets the positioning with velocity control mode.
SL1: Torque control mode
SL2: Velocity control mode
SL3: Position control mode
l
Either one of positioning with the RS-232C analog command or the analog velocity command
may be selected in the velocity control mode.
The parameter AC selects the way of positioning.
AC0 : Analog command invalid. DC command is valid.
AC1 : Analog command valid. When analog velocity command is +: CCW direction
AC–1 : Analog command valid. When analog velocity command is –: CW direction
6.3.1. RS-232C Position Communication Command Operation
l
Motor velocity may be controlled directly through the RS-232C command in the velocity control
mode.
l
The parameter AC (AC0) sets validity of DC command.
Inputting as
C D

will make the Motor controlled with the velocity that is proportional to the data.
l
Relation between the data of DC command and the velocity is shown in Figure 6-25.

Caution: When the DI parameter reverses the sign of coordinate, the polarity of
the DC command is reversed as well.
