Kollmorgen/DANAHER AHD70E4-44S motor winding

When using a drive other than the Kollmorgen AKD you will need to account for the difference (Delta) in temperature between the value reported by the thermal sensor and the actual motor winding temperature. This is necessary to insure proper operation and protection of the motor. The provided graph shows the delta between the reported device temperature on the x axis and the motor winding temperature on the y axis and should be used to adjust the response of the system for the difference between the thermal sensors reported temperature and the actual motor winding temperature.

The holding brake is designed to provide static holding torque to the motor shaft with the brake coil de-energized. The brake must first be released (coil energized) prior to commanding motor rotation as determined by its drop-out time. The brake is intended for holding or “parking” of a stationary motor. It is not intended for dynamic braking. There should be absolutely no motion of the rotor when power is removed from the brake coil.

Note 1: AKD drives have a resolver measurement accuracy of ±45”, for a drive w/ motor accuracy of ±585” and RMS Noise of ±9.9” Accuracy & RMS Noise data when used with other drives may be different.
Note 2: Accuracy refers to overall system accuracy once installed in the motor. Noise refers to the RMS position noise when at stand-still.
Note 3: Motor ID support means electronic motor nameplate data is included, allowing for plug-and-play commissioning.
Note 4: At the time of printing, this information was not available. Please contact Kollmorgen Customer Support for the latest update.
Note 5: AKM2G-LV Size 2 models are only available in single-connector configurations.

With positive DC current into phase W and out of phase V (U floats) the resolver is aligned to electrical ±5 counts. ie. Voltage S1-S3 set to null voltage S2-S4 max in phase with reference (R1-R2).
