blinking, toggle (on then off) the
Clear Error %Q
bit (%Q1 for this configuration) in the PLC
data table. Conditions that continue to cause an error must be corrected in order to clear the

Jogging With the Motion Mate DSM314
The
Jog Velocity
,
Jog Acceleration
, and
Jog Acceleration Mode
are configurable in the DSM314 module.
These values are used whenever a
Jog Plus
or
Jog Minus
%Q bit is turned ON. Note that if both Jog bits are
ON, no motion is generated. Default values for jog velocity were set during configuration.
A
Jog
can be performed when no other motion is commanded. The
Enable
Drive
%Q bit does not
need to be ON to Jog. Turning on a
Jog
%Q bit will automatically turn on or enable the servo. You
should hear the amplifier enable and the motor will have torque on the shaft. Conversely, the drive
will automatically disable when the jog bit is released.
To jog the axis in the positive direction, toggle ON %Q0021 for axis 1 or %Q0037 for axis 2. Note
that the references used here are for %Q references starting at %Q0001. The starting %Q reference
is configurable.
If the motor will not jog, skip over this section and go to Section 6, "Troubleshooting Your Motion
System."

Configuration Settings
If your system powers up with alarms, it may be due to an incorrect configuration setting.
The Series 90-30 PLC configuration must be stored to the PLC CPU and the PLC must be in
Run/Output Enabled mode.
If you cannot move an axis or execute a jog, check to see that all conditions necessary to perform
these operations are met. Refer to the appropriate areas in this manual.
