In addition to Jog, Index, and Home functions, the EP-I drive provides three basic modes of operation in Alternate Mode: Analog Velocity, Analog Torque, and Pulse Mode.

When in Alternate Mode the drive will ignore all Index, Home, or Jog initiate requests. If the drive is indexing, homing, or jogging when alternate mode is turned on, the drive will initiate a stop command and use the stop decel to ramp down to zero, then it will switch into alternate mode.
