Parameter Descriptions

Fault Counts Fault.#.Counts

The module stores the total number of times the specific fault has occurred since it was

manufactured.

Module Faults Bitmap Fault.ModuleFaultsBitmap

This parameter is a 32-bit register which holds all of the module fault status bits. Following

is a list of all module faults and their associated bit numbers:

0 = Module watchdog timer fault

1 = Module invalid configuration fault

2 = Module NVM invalid fault

3 = Module power up self test fault

4 = Module following error fault

5 = Module travel limit plus

6 = Module travel limit minus

7 = Module program fault

All other bits are not used. A "1" in these bit locations indicates the specific fault is active,

and a "0" is inactive.

Reset Faults Fault.Reset

Resets faults that do not require a power down. This event is "or"ed with the reset button on

the drive.

Enable Feedforwards FeedforwardsEnable

This parameter may be setup on the Tuning view or through a program, and enables

feedforward compensation. When feedforwards are enabled, the accuracy of the Inertia and

Friction settings are very important. If the Inertia setting is larger than the actual inertia, the

result could be a significant overshoot during ramping. If the Inertia setting is smaller than

the actual inertia, following error during ramping will be reduced but not eliminated. If the

Friction is greater than the actual friction, it may result in velocity error or instability. If the

Friction setting is less than the actual friction, velocity error will be reduced, but not

eliminated.

Feedhold Feedhold

When this destination is activated the motor will decelerate to a stop in the time specified by

the FeedholdDecelTime parameter. When it is deactivated the motor will accelerate back up
