Supply voltage for MOVILINK® DDI electronics
The motor-integrated electronics of MOVILINK® DDI are generally supplied with a voltage of 24 V by an inverter from the MOVI-C® modular automation system. The inverters provide at least 150 mA of current. Depending on the 24 V configuration of the entire drive train, and taking the optional equipment of the motor and the selected inverter into account, the inverter may require an external 24 V backup voltage supply.
The following table provides an overview of the options of the MOVILINK® DDI modular system. The listed values are maximum permitted values that may be required by the options at the minimum permissible supply voltages.
Option | Power demand 24 V supply via MOVILINK® DDI |
|---|---|
Without encoder | 60 mA |
EI8Z built-in encoder | 115 mA |
Encoder EK8Z | 110 mA |
Encoder EK9Z | 110 mA |
Encoder AK8Z | 110 mA |
EK8Z safety encoder | 120 mA |
EK9Z safety encoder | 120 mA |
AK8Z safety encoder | 120 mA |
Integrated BG1Z brake control | 40 mA |
DriveRadar® SensorModule DU1Z | 25 mA |
Example:
A motor with MOVILINK® DDI and EI8Z built-in encoder and integrated brake control has an electronics current demand of 155 mA and must be operated with an additional backup voltage.
