1213 Profile Command
Profile Command
RW 32-bit
Integer
Sets bits to configure the speed profile/position indexer control logic.
Bit 0 “StrStepSel0” – Bit 0 through Bit 4 set initial or starting step in the move table in binary format. A starting step value of zero results in no motion when the
drive is enabled.
Bit 1 “StrStepSel1”
Bit 2 “StrStepSel2”
Bit 3 “StrStepSel3”
Bit 4 “StrStepSel4”
Bit 8 “Hold Step” – When the drive is enabled with this bit is set, the drive starts and runs at zero velocity. The starting step is not executed until the “Hold Step” bit
is removed. For non-blended moves, the drive will hold zero speed and/or current position. This does not stop the drive. For blended moves, the drive will continue
to run at the step velocity. If the Hold Step bit is removed, then the conditions required to complete the step can be evaluated.
Bit 9 “Vel Override” – Can be used to rescale all move velocities by the velocity override P1216 [ProfVel Override]. When this bit is off, a scale factor of 1 is used.
Bit 10 “Restart Step” – Can be used to disable a currently executing profile. This bit forces the current step to reset to the starting step value.
Bit 11 “HomNotSetAlm” – Sets condition to indicate the “home position not set” alarm. The absolute position type will work without home position if the bit is off.
Default state is Enabled.
Bit 12 “Prof Run Alm” – Sets condition to indicate the profile running alarm when the drive is running. Default state is Enabled.
1215 Counts Per Unit
Counts Per Unit
Sets number of position feedback counts per unit of machine travel (for example 1024
encoder edge counts per inch). This parameter is used to scale position targets from
their entered values of units to internal units of encoder edge counts. This parameter is
also used to convert actual motor position from encoder edge counts back into the
desired units for display in P1212 [Units Traveled].

1216 ProfVel Override
Profile Velocity Override
Sets multiplier for all move velocities when the velocity override function is selected
P1213 [Profile Command] Bit 9 “Vel Override.” This parameter is typically set to a value
less than 1. When the velocity override bit P1213 [Profile Command] Bit 9 “Vel Override”
is off, a scale factor of 1 is used.
