196 Digitax ST Advanced User Guide
www.controltechniques.com Issue Number: 1
If an error occurs the reason for the error is written to this parameter and the drive may produce a SL3.Er trip. A value of zero indicates that the Motion
Processor has not detected an error, a non-zero value indicates that an error has been detected. (See Table 5-14 on page 196 for the meaning of the
values in this parameter.) When the drive is reset this parameter is cleared.
The Motion Processor includes a temperature monitoring circuit. If the PCB temperature exceeds 90°C the drive fan is forced to operate at full speed
(for a minimum of 10s). If the temperature falls below 90°C the fan can operate normally again. If the PCB temperature exceeds 100°C the drive is
tripped and the error status is set to 74.
The software version is displayed in these parameters in the form Pr 17.02 = xx.yy and Pr 17.50 = zz. Where xx specifies a change that affects
hardware compatibility, yy specifies a change that affects product documentation, and zz specifies a change that does not affect the product
documentation.

Digitax ST Parameter Access Error -
Parameter is Write Only
The Digitax ST Menu Parameter that
you are trying to read from is Write
Only
Avoid reading from Write Only parameters.
Use Drive Menu Watch view in PowerTools
Pro, or Digitax ST User Guide to verify
parameter accessibility

Digitax ST Parameter Access Error -
Written Value Out of Range
The value you are trying to write to the
Digitax ST Menu Parameter is out of
range.
Modify value that you are trying to write so
that it is within valid range of the parameter.
Use the Digitax ST User Guide to verify the
range of the parameter and try again

Select lower switching frequency in
PowerTools Pro configuration, or reduce
motion performance (i.e. lower accel/decel,
lengthen dwells). If problem persists, please
contact factory

104 Y Following Error
Amount of following error exceeded
following error limit set in PowerTools
Pro software.
Increase Following Error Limit in PowerTools
Pro configuration. Increase Velocity Loop

in PowerTools Pro configuration. Lower
Acceleration/Deceleration ramp values.
Make sure that programmed velocity is
within maximum operating speed of the
given motor.
