Description
One module gives up to 1 850 A, and higher currents are reached by connecting frame size 2 drives in parallel through special ports. The power section is supplied from 3×24–480 V, 3×500–575 V or 3×500–690 V AC, the maximum output voltage is 760 V DC for the 690 V version, and the auxiliary supply is 208–480 V AC. The built-in field controller is rated for 8 or 20 A, and for large motors there is the external FXMP25 for 25 A, which is controlled through an RJ45 connector or works standalone. The power section is combined with the Unidrive control platform, so the RS485 port with Modbus is standard, and the three slots accept 19 modules, including EtherCAT, PROFIBUS DP-V1, PROFINET, Interbus, DeviceNet, Ethernet and CANopen. Frame sizes are 1A, 1B and 2A–2D, and the field circuit fuses are in removable holders. The drive carries the CE mark and a 24-month warranty according to the manufacturer.
How to choose
The armature current determines the frame size and number of modules. Up to 1 850 A one drive is enough, and above that frame size 2 units are connected in parallel. For unidirectional machines the 1Q version is used, and for reversing and regenerative ones the 4Q. Field current up to 8 or 20 A is covered by the built-in controller, and for more the external FXMP25.

FAQ
What armature current is Mentor MP made for?
From 25 to 7 400 A. One module delivers up to 1 850 A, and higher currents come from parallel connection of frame size 2 drives.
What supply voltage does Mentor MP have?
The power section is 3×24–480 V, 3×500–575 V or 3×500–690 V AC, and the auxiliary supply is 208–480 V AC. The maximum output voltage is 760 V DC for the 690 V version.
What field current can Mentor MP supply?
The built-in controller is rated for 8 or 20 A. For large motors there is the external FXMP25 controller for 25 A.
How do single-quadrant models differ from four-quadrant ones?
Single-quadrant 1Q models are unidirectional, and four-quadrant 4Q models are reversing and regenerative.
Which modules can be installed in Mentor MP?
The three slots accept 19 modules, including SM-Applications, SM-Register, encoder, communication and input-output modules. RS485 with Modbus is standard.
