The latest release of Athena software includes support for the entire Panasonic MINAS series motors. This includes motors and encoders from the earliest Minas A series drives (Legacy-MFE2500 and MFE0017 encoders), Minas A4 (MFE2500-serial and MFE0017), Minas A5 (MFE0020 and MFE0017), and Minas A6 series as well (MFE0023).
Like other Japanese motor brands, Panasonic offers serial encoders in different resolutions that can be "Incremental", meaning single-turn serial encoder with no battery backup, or "Absolute", meaning multi-turn serial encoder with battery backup. The earliest Minas A series also has a legacy encoder with actual incremental outputs (ABZ + Rx), so the terminology can be a bit confusing. See below for detailed info among the several different series.

Standard Panasonic motor wire colors:
U=Red, V=White, W=Black, GROUND=Green
The Panasonic motors all use a standard alignment. The angles listed below are used with any of the serial encoders. The legacy MFE25000 11-wire incremental alignment is slightly different and can be found in this article: https://support.mitchell-electronics.com/hc/en-us/articles/8831729196443
+U-V = 240E
The MFE2500 (5-wire) and MFE0020 serial encoders are both "incremental", meaning serial encoders without battery backup. These encoders come with commutation tracks since it cannot produce an absolute position at startup. While they still use the same alignment angles listed above, the commutation states should also tested and alignment verified.
U V W
+U-V: H/L H L
+U-W: L H L/H
The serial MFE encoders have memory storage capability, and our latest Panasonic Memory Test can read the data that Panasonic programs into them. This data is minimal, typically consisting of only the motor model type and power rating. We include the standard Panasonic alignment in the memory report, although it is not written in the data itself.
It is important to consider the memory data if you are replacing encoders. You should be using an encoder from a motor of the same model type. Currently we do not offer memory programming for MFE encoders, but we are planning on offering it in the future.
Any of the 7-wire serial encoders will come with battery lines. The battery is stored in the drive itself, or somewhere else on the machine. If the encoder battery voltage drops below 2.5VDC, the encoder will produce a BATTERY ALARM will also trigger the BATTERY ERROR alarm. To test and clear these alarms, simply connect the free battery wire on our test cable to J1 pin 1 (+5VDC) to simulate a battery connection. Once connected, click the "Reset Errors and Multi-turn" button to clear any battery alarms.
The OVERFLOW box will show ALARM when the multi-turn counter overflows its range. This alarm must be cleared by a reset using the same "Reset Errors and Multi-turn", which should then clear it to OK.
If any of these alarms cannot be cleared then it could indicate a defective encoder.
The latest TI-3000JX software contains all serial MFE encoder selections under the Generic MFE selection. Panasonic motors should have a CW forward direction and the serial encoders have a CCW forward direction. This means the Direction option in Setup should be set to Opposite (D:O).
The legacy MFE2500 incremental 11-wire encoder can be run using the Generic Encoder selection. The Setup will be 10,000 counts and the Direction option set to Same (D:S)
Motor Model Designation and Encoder Type
The table below shows the breakdown for these earliest series motors. They can come equipped with MFE0017 serial encoders (Absolute 17bit, 7-wire) or a legacy MFE2500 incremental encoder (2500P/r, 11-wire). These legacy types have their own separate article on testing, found here: https://support.mitchell-electronics.com/hc/en-us/articles/8831729196443
The table below shows the breakdown for the Minas A4 series motors. They can come equipped with MFE0017 serial encoders (Absolute 17bit, 7-wire) or MFE2500 serial encoder (2500P/r, 5-wire).
The table below shows the breakdown for the Minas A5 series motors. They can come equipped with MFE0017 serial encoders (Absolute 17bit, 7-wire) or MFE0020 serial encoder (Incremental, 5-wire).
The table below shows the breakdown for the Minas A6 series motors. They come equipped with MFE0023 serial encoders only (Absolute 23bit, 7-wire).
