Motor current in percentage of maximum
current
(0..100% * IDX max. current). Refer 6.2.1.2
Provides failure readout. Refer 6.2.1.3
In mode 0 (SPI) the StallGuard feature is
functional. ‘g’ provides the actual StallGuard
value, not the setting. Refer 6.2.1.4
Used to switch on and off reference run
values. Refer 6.2.1.5
Select chopper mode: 0:SPI (default), 1:PWM,
2:PHASE, 3 & 4: Combinations, Refer 6.2.2
Output adjustments, Refer 6.2.1.6
Provides out of the I/O the values of the ports
GPI, REF_A, REF_B, GPO and ALARM. Refer
6.2.1.7
Provides the current position of the motor
Capital letter followed by the command ‘S’
makes this letter the new address byte
Sets the RS485-Timeout
Sets baud rate for RS485 communication.
Refer to 6.2.1.8
Velocity for rotation / reference run
v = n * 0.149157 usteps/s
Additional Parameter is 0 or missing: Carriage
Return (CR) comes after acceleration phase
Additional Parameter is 1: no delay of CR
Stores different parameters to the EEPROM to
restart with the same performance. Refer
6.2.1.9
Provides version number of implemented
Software
Sets 0..100% of maximum current after 1
second motor inactivity. For no standby current
use the same value as for “Set motor current”.
Sets the maximum microstep resolution (0:
max; 4: min), Refer 6.2.1.11
