Reference switch
tolerance
For three-switch mode: a position range,
where an additional switch (connected to
the REFL input) won't cause motor stop.

Soft stop flag
If cleared, the motor will stop immediately
(disregarding motor limits), when the
reference or limit switch is hit.

Ramp divisor
The exponent of the scaling factor for the
ramp generator- should be de/incremented
carefully (in steps of one).

Pulse divisor
The exponent of the scaling factor for the
pulse (step) generator – should be
de/incremented carefully (in steps of one).

Step
interpolation
enable
Step interpolation is supported with a 16
microstep setting only. In this setting, each
step impulse at the input causes the
execution of 16 times 1/256 microsteps. This
way, a smooth motor movement like in 256
microstep resolution is achieved.
0 – step interpolation off
1 – step interpolation on

Double step
enable
Every edge of the cycle releases a
step/microstep.
It does not make sense to
activate this parameter
for internal use.
Double step enable can be used with Step/Dir
interface.
0 – double step off
1 – double step on

Chopper blank
time
Selects the comparator
blank time
. This time
needs to safely cover the switching event and
the duration of the ringing on the sense
resistor. For low current drivers, a setting of 1
or 2 is good.

Chopper mode
Selection of the chopper mode:
0 – spread cycle
1 – classic const. off time

Chopper
hysteresis
decrement
Hysteresis decrement setting. This setting
determines the slope of the hysteresis during
on time and during fast decay time.
0 – fast decrement
3 – very slow decrement

RW

Chopper
hysteresis end
Hysteresis end setting. Sets the hysteresis end
value after a number of decrements.
Decrement interval time is controlled by axis
parameter 164.
-3… -1 negative hysteresis end setting
0 zero hysteresis end setting
1… 12 positive hysteresis end setting
