Gererell:
*It is not recommended to change from STEP MODE to FIX SPEED mode. It is better to stop the engine first and then change the mode. *However, when changing from one of these two modes to DISABELD mode, the motor will simply coast to a stop without any braking effect (all windings will be non-magnetized). *When resetting the modules, the motor keeps the current step (The windings are still magnetized). *Attention: The acceleration is divided by two within the module. Since the motor accelerates with each trigger edge. Therefore the LSB is not considered by the acceleration. *An interrupt is triggered when the motor has completed the shutdown and changes normally to the stop state.
DISABELD (RESERVED):
The motor is freewheeling here. This means that the motor has no holding torque (all windings are not magnetized).
STEP MODE:
The motor moves through the specified number of steps. It uses a ramp to accelerate up and down. changes in the configuration, prescaler and steps registers are only applied when the motor is at standstill. The module sends a signal to reset the start bit (osl_reset_start_bit). When the start bit is manually reset, the motor immediately ramps down without reaching the number of steps.
FIX SPEED:
The motor ramps up to a preset speed. When the command to stop is given, the ramp is lowered again until it comes to a standstill. Changes in acceleration and starting speed are only applied at standstill. The maximum speed can be changed at will. Any change in maximum speed is approached with a ramp.
