A practical limit with most stepper motor types is about 20 rotations / second in chopper mode 0 and 5
rotations / second in chopper mode 2.
As a second parameter, value “0” or “1” is optional. Standard is 0 and sends back the Carriage Return
character at once. If it is set to “1” sending back of the Carriage Return character is delayed until the
target velocity is reached.
Example:
AV –50000 ⇒ ENTER: Accelerates motor to given velocity
AV 0 1
6.2.1.11
This command stores different parameters to the EEPROM to restart with the same performance after
power down.
The stored parameters are:
6.2.1.12
The microstep resolution can be set by the user. It depends on the maximum resolution witch differs in
the three chopper modes (see 6.2.2).
The maximum resolution is divided by the parameter ‘Z’.
*) Simulated microsteps, the actual microsteps of the motor are not improved.
Example:
AZ 2 ⇒ ENTER : Sets the microstep resolution to a quarter of the maximum resolution.
6.2.2 Chopper Modes
6.2.2.1 Chopper Mode 0 (SPI) / Default Mode
In this mode, the motor coil current is regulated on a chopper-cycle-by chopper-cycle bias. This is the
standard operation mode for most motor drivers. It brings a medium microstep resolution of 16
microsteps and typically works good with most motors and a high range of supply voltage and motor
current settings. A resolution of up to 64 microsteps can be simulated but the motor precision is not
improved compared to 16 microsteps.

The minimum supply voltage has to be above two times the nominal motor voltage.
