Chapter 10 Modes of Operation
VPL (DI code: 0x0C) Latch Function of Analog Position Command
If this digital input (DI) is on, motor position is held at the current position
when the DI is triggered. During DI on, the motor does not operate, even when
there is a change of analog command. When this DI is off, the motor completes
the command that is changed during the time when the DI is on.
VPRS (DI code: 0x0D) Clear Function of Analog Position Command
If this DI is on, motor position is held at the current position when the DI is
triggered.
Even if the analog command changes while the DI is on, the motor remains at the
current position, which includes when the DI is off. However, the current motor
position corresponds to the new analog command. Thus, the analog input
command redefines the coordinate system of the motor.
