Table 13.
The available range for both parameters is from 0.5 µs to 8 µs.
Table 14.
Any attempt to write to the register when the motor is running causes the command to be
ignored and NOTPERF_CMD to rise (see
TON_MIN
The TON_MIN register contains the minimum ON time value used by the current control
system (see
The available range for both parameters is from 0.5 µs to 64 µs.
