Command ‘X’ and ‘x’: firmware revision number
The ‘X’ command and the ‘x’ command print out the firmware revision number and also the actual
temperature and the actual supply voltage of the device.
5.4.19
Command ‘Y’ and ‘y’: standby current setting
The ‘Y’ command sets the standby current. The parameter range is 1..8, where 1 means 1/8 and 8
means 8/8 (100%) of the run current (set by the ‘C’ command or the DIP switches). The power-on
setting can be set using the DIP switches.
The ‘y’ command prints out the actual standby current setting.
5.4.20
Command ‘Z’ and ‘z’: change microstep resolution
The ‘Z’ command changes the microstep resolution. The ‘z’ command outputs the actual microstep
resolution. The power-on setting can be set using the DIP switches.

Table 5.10: Adjustment of Microstep Resolution
*) Simulated microsteps, the actual microsteps of the motor are not improved.
**) Simulated microsteps, the actual microsteps are improves but do not reach 32 microsteps.
Example:
AZ 2
ENTER : Sets the microstep resolution to a quarter of the maximum resolution.
5.4.21
Command ‘@’: change RS485 address
This command changes the RS485 address letter. The new address letter must follow this command
immediately (without any spaces in between).
To change the address letter of a TMCM-078 module from ‘A’ to ‘X’ type A@X then press ENTER.
