230V FX Series Positioning Drive Reference Manual
The number of home parameters shown in the home screen will change depending on the
Home Type selected. A maximum of two Home cycles can be programmed with an FX drive
(Home #0 and Home #1). However, most applications require only one home function.
Lock
The Home Lock feature is available to prevent all motion (except Jog) from being initiated
before a home cycle has been completed. When powering up an FX drive with the Home Lock
feature “ON”, all motion (except Jog) cannot be initiated by serial commands or through
inputs until a Home Cycle has been completed. To prevent Jog motion from occurring, both
the Jog Lock and the Home Lock must be on.
To enable the lock features, logic power must be re-cycled to the drive after the Home
Lock and Jog Lock features have been turned on.
Accel Time and Decel Time
Each Home, 0 and 1, has a Accel Time and a Decel Time that are used for all home types even
if they are not displayed in PCX. If the Decel Time is not displayed in PCX for the selected
Home Type, switch to a Home Type which does show it to set the Decel Time. The Accel
Time range is 0.008 to 65.535 Seconds with a default of 1.000 Second. The Decel Time range
is 0.008 to 65.535 Seconds with a default of 1.000 Second.
Resolver Offset
Resolver Offset function is the distance in user units within one revolution between resolver
zero and the mechanical zero point for your machine.
Reference Position
The Reference Position is the distance from the Homed position to the user defined zero point
of the machine.
After the Home cycle is complete the position counters are set to zero. Then the value in
Reference Position is loaded in the memory. This configures the drive to know the difference
between Zero Home Position and Machine Zero. The FX drive will move the motor in
relation to the user defined home point of the machine.
Home Limit Distance
This parameter limits the incremental distance that the motor travels during a home move in
looking for a Home Sensor Input. If this limit is exceeded, the Sensor Limit Distance Hit
output is turned on and the home operation is aborted.
