Abstract

A drive control system includes a drive device that has a stepping motor and a displaceable part, and a control device. The control device outputs a first command to the stepping motor to displace the displaceable part in a first direction, performs a first determination to determine a step-out of the stepping motor based on the first command, and at the position where the displaceable part has finished displacing based on the first command, outputs a second command to the stepping motor to displace the displaceable part in a second direction different from the first direction, performs a second determination to determine a step-out of the stepping motor based on the second command, and if the stepping motor is in a first state where it steps out both when it receives the first command and when it receives the second command, outputs a first abnormality signal indicating the first state.

Dependent claims

A drive control system, comprising:

a drive device;
and
a control device configured to control the drive device,
wherein the drive device comprises:
a stepping motor configured to rotate upon receiving a command from the control device;
and
a displaceable part connected to the stepping motor and configured to be displaced by rotation of the stepping motor,
and wherein the control device is configured to:
output a first command to the stepping motor to displace the displaceable part in a first direction;
perform a first determination to determine a step-out of the stepping motor based on the first command;
at a position where the displaceable part has finished displacing based on the first command, output a second command to the stepping motor to displace the displaceable part in a second direction different from the first direction;
perform a second determination to determine a step-out of the stepping motor based on the second command;
and
if the stepping motor is in a first state where it steps out both when receiving the first command and when receiving the second command, output a first abnormality signal indicating the first state.
