Siemens SIMATIC MICRO-DRIVE PDC600 - Calculating the Overload Capability of the Power Unit

WARNING
Operation above the voltage setting range
Under the given application conditions, ensure that the motor is not operated above the
voltage setting range by selecting the appropriate motor and gear unit; otherwise, the DC-link
voltage can increase above 60V DC with inactive control.
Reference
Note the detailed information on the power supply in the System Manual SIMATIC MICRO-DRIVE
Drive controller PDC (https://support.industry.siemens.com/cs/ww/en/view/109797859).
