If Pr x.49 is set to one, Pr x.04 and Pr x.05 are not updated. If this parameter is zero, Pr
x.04 and Pr x.05 are updated normally.
The error status is provided so that the only one option error trip is required for each
Solutions Module slot. If an error occurs, the reason for the error is written to this
parameter and the drive may produce a ‘SLX.Er’ trip, where x is the slot number. A
value of zero indicates that the Solutions Module has not detected an error, a non-zero
value indicates that an error has been detected. (See Chapter 7 Diagnostics for the
meaning of the values in this parameter.) When the drive is reset, this parameter is
cleared.
This Solutions Module 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.
