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.
Normally leave at the default value.

Constant TOff
mode
Selection of the chopper mode:
0 – spread cycle
1 – classic constant off time

Disable fast
decay
comperator
See parameter 163. For ”classic const. off time”
setting this parameter to ”1” will disable current
comparator usage for termination of fast decay
cycle.

Chopper
hysteresis end /
fast decay time
See parameter 163. For ”spread cycle” chopper
mode this parameter will set / return the hys-
teresis end setting (hysteresis end value after a
number of decrements). For ”classic const. off
time” chopper mode this parameter will set /
return the fast decay time.

Chopper
hysteresis start
/ sine wave
offset
See parameter 163. For ”spread cycle” chopper
mode this parameter will set / return the Hys-
teresis start setting (please note that this value is
an offset to the hysteresis end value). For ”clas-
sic const. off time” chopper mode this parameter
will set / return the sine wave offset.

Chopper off
time (TOff)
The off time setting controls the minimum
chopper frequency. An off time within the range
of 5µs to 20µs will fit.
Off time setting for constant t Off chopper:

(Minimum is 64 clocks)
Setting this parameter to zero completely dis-
ables all driver transistors and the motor can
free-wheel.
