Setting of MP_ampBusVoltage:
Regenerative module ((4) in commissioning flow chart)
The DC-link voltage for regenerative power modules are independent of the
line voltage UNetz. On regenerative HEIDENHAIN power modules it is 650 V
(MP_ampBusVoltage = 650) and on the regenerative Siemens modules 600
V or 625 V (MP_ampBusVoltage = 600 / 625).
Default setting of MP_ampVoltProtection has been made
Regenerative module

YES
Stationary line voltage stable?
MP_ampBusVoltage = smallest
