Operation by hMT Modes

LMD CANopen
hMT Off (Bypass)
With hMT disabled, the motion block of the device will operate as a standard integrated stepper
controller/drive/motor.
Commands for absolute or relative positioning, or slew at velocity are received via the CAN bus
and processed as commanded, bypassing the hMT logic block.
The following graphic shows a block diagram for a system with hMT disabled:

In bypass mode, the current control will be fixed at the set run and hold current percent levels.
Encoder functions such as stall detection and position maintenance are available in bypass
mode, provided that the LMD model is equipped with an encoder.
