Rexroth MAD & MAF Asynchronous Motors – Mitchell Electronics Inc

Overview

The Rexroth MAD motor series are air-cooled asynchronous (spindle) motors. The MAF series are the liquid-cooled versions. These newer Rexroth models replace the legacy 2AD, ADF, and ADP series from Indramat. Like any asynchronous spindle motor, they do not require alignment of the feedback device, and they cannot be run on our TI-3000JX.

Encoders

Below you will find a table with the different encoders that can come equipped on these motors. The "I2C" interface is used on the legacy Indramat encoders (M0, N0, and S0) found on the legacy 2AD motor series.

Feedback Connections

Once the feedback device is identified from the above table, you can reference the pinouts below depending on the type code.

Image 2 "Incremental Encoder Option (C0)".

Our cable TI-5010 used in Siemens motors with ERN1387 encoders can also be used with the incremental encoders on these series. The commutation lines (C & D) in our cable are not present on this motor and you will only obtain reading for the incremental lines (A.B and Z).

Image 3 "I2C Encoder Option (M0/S0)".

For the I2C interface, the TI-5021 test cable and TI-5104 adapter module are used. You can also connect directly to the encoder with the TI-5076 test cable and module.

Image 4 "EnDat 2.1 Option (M2/S2)".

For the EnDat2.1 interface, the TI-5093 test cable and TI-5104 adapter module are used. You can also connect directly to the encoder with the TI-5079 test cable.
