current position (the PA1_12 (Z-phase position offset) parameter is
automatically rewritten).
* The Z-phase position cannot be set under the following conditions.

When PA2_74 (parameter write protection) is set to "1: Write protect".

At such times, rotate the motor shaft twice or more.
By pressing the [Offset Adjust] button, the analog input VREF terminal and
TREF terminal offsets are adjusted (The PA3_32 (speed command offset)
and PA3_34 (torque command offset) parameters are automatically
rewritten). Please note that offset adjustment is not possible when
PA2_74 (parameter write protection) is set to "1: Write disable".
