YES
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).
YES
MP_ampBusVoltage = 650 (4)
– Calculation of minimum line voltage (5)
– Series reactor taken into account
– Line voltage at machine installation site
taken into account
No
MP_ampBusVoltage = smallest
value of stationary DC-link voltage (6)
No
MP_ampBusVoltage = smallest
value of dynamic DC-link voltage (7)
