memory.

6.4.9 Status information

This parameter controls access via the drive keypad as follows:

The keypad can adjust this parameter even when user security is set.

The parameter displays the software version of the drive.

Each bit in this parameter has the following functions:

Example

00.051

= 8 (1000

binary

) Th Brake Res trip is disabled

00.051

= 12 (1100

binary

) Th Brake Res and phase loss trip is disabled

Stop on non-important trips

If bit 0 is set to one the drive will attempt to stop before tripping if any of
the following trip conditions are detected: I/O Overload, An Input 1 Loss,
An Input 2 Loss or Keypad Mode.

Disable braking resistor overload detection

For details of braking resistor overload detection mode see Pr

10.030

Disable phase loss trip

Normally the drive will stop when the input phase loss condition is
detected. If this bit is set to 1 the drive will continue to run and will only
trip when the drive is brought to a stop by the user.

Disable braking resistor temperature monitoring

Size 3, 4 and 5 drives have an internal user install braking resistor with a
thermistor to detect overheating of the resistor. As default bit 3 of
Pr

00.051

is set to zero, and so if the braking resistor and its thermistor

is not installed the drive will produce a trip (Th Brake Res) because the
thermistor appears to be open-circuit. This trip can be disabled so that
the drive can run by setting bit 3 of Pr

00.051

to one. If the resistor is

installed then no trip is produced unless the thermistor fails, and so bit 3
of Pr

00.051

can be left at zero. This feature only applies to size 3, 4 and

5 drives. For example if Pr

00.051

= 8, then Th Brake Res trip will be

disabled.

Disable parameter freeze on trip

If this bit is 0 then the parameters listed below are frozen on trip until the
trip is cleared. If this bit is 1 then this feature is disabled.
