Overview
The new Mitsubishi Melservo J5 series drives use motors that come equipped with a new 26-bit resolution battery-less absolute position encoder. The removable type encoders are labeled as CSW26K and the built-in types are labeled CBW26K. We now support testing and running from these new encoders, just the same as all previous Mitsubishi serial selections.
Along with the higher count resolution, these encoders utilize a brand new battery-less backup system "powered by a unique self-power-generating structure", as listed in the Mitsubishi brochure. No battery wires or batteries housed in the drive that can expire. This encoder stores battery voltage from an onboard generator.
The HK-MT series motors use a 26-bit (incremental encoder) that has a different encoder ID. We have labeled these encoders as CBW/CSW26K INC, as opposed to the more common CBW/CSW26K ABS encoders found on most of the J5 series. After testing the two types of encoders (INC and ABS), we have determined that both models contain the battery-less system and 16 bits of multiturn counts. However, when the drive sees the Encoder ID of the INC models, it simply ignores the multiturn count.
J5 Series Rotary Motor Models
HK-KT, HK-MT, HK-RT and HK-ST
Encoder Connections:
HK-ST series and HK-RT use a standard 10 pin DDK. This matches our TI-5732 test cable.
HK-KT, HK-MT and HK-RT use a new hybrid style connector. This matches our TI-5772 test cable.
J5 Series Linear Motor Models
LM-H3, LM-AJ, LM-F, LM-K2 and LM-U2.
The "Linear Servo Motors" will have a wide range of different linear encoders that will either have "Mitsubishi Electric serial interface compatible" or A/B/Z differential output type, below there's a list with the different manufacturers listed:
J5 Series Direct Drive Motor Models
TM-RG2M/TM-RU2M and TM-RFM
The "Direct Drive Motors" will come with a Absolute/incremental 20-bit encoder (resolution: 1048576 pulses/rev). The manual doesn't specify the pinouts for these motors.
