Factory settings: run current: F / stop current: 3
The stop current is normally set to 40 to 50 % of the run current, to keep the motor
temperature as low as possible.
The table values refer to current values, if both motor phases are activated. The
current in one phase is calculated as: table value x

Maximum run current/stop current : 8.4 A x

x 1.3 = 15.4 A

If step resolution or current shaping are changed during power-on, the switch
position of the MSD2
