18.5.2.2 Bit definition of Control DI
Control DI can control the FSA state and issue control commands. The following table shows the bit definition
of Control DI.

C_CDP
Gain switching
Turn on C_CDP to use the values of [Pr. PB29] to [Pr. PB36] and [Pr. PB56] to [Pr.
PB60] as the load to motor inertia ratio and gain values.
5
C_CLD
Fully closed loop control switching
Use this bit when the semi closed loop control/fully closed loop control switching is
enabled with [Pr. PE01].
Turn off C_CLD to select the semi closed loop control, and turn on C_CLD to select the
fully closed loop control.

C_PC
Proportional control
Turn C_PC on to switch the speed amplifier from the proportional integral type to the
proportional type.
If the servo motor at a stop is rotated even one pulse due to any external factor, it
generates torque to compensate for a position mismatch. When the servo motor shaft
is to be locked mechanically after positioning completion (stop), switching on the C_PC
upon positioning completion will suppress the unnecessary torque generated to
compensate for a position mismatch.
When the shaft is to be locked for a long time, use the C_PC and torque limit at the
same time to make the torque less than the rated torque.

The value at reading is undefined. Set "0" at writing.
