Description
An external pot is connected and
the common side of the pot is
open. The drive generates this
fault when the voltage between
pot leads is greater than 3.9V DC.
A SCANport device requests a
Read or Write of a data type not
supported. This will also occur if:
1. [Motor Type] is set to “Sync
PM” and [Stop Mode Used] is
set to “DC Brake”, or
2. [Motor Type] is set to “Sync Reluc” or “Sync PM” and [Speed
Control] is set to “Slip Comp”.

Action
Check the external potentiometer circuit at TB2 for an open circuit.
Check programming.
Remove or relocate to proper slot.
Check for a short circuit at the drive
output or excessive load conditions at
the motor.
An excessive motor load exists. It
must be reduced such that drive output current does not exceed the current set by the [Overload Amps]
parameter.
