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. For higher current applications
like the TMCM-1311 a setting of 2 or 3 will be
required.

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

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

hysteresis start
Hysteresis start setting. Please remark, that this
value is an offset to the hysteresis end value.

Chopper off time 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

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