* When Load Share is enabled, Proportional & Integral Control (L7-07 = 1) and Proportional
Only (L7-07 = 0) are invalid as the setting of L7-07 (Torque Limit during Accel/Decel).
 Load Share is disabled when the following references are input. Ensure that the following
references are simultaneously input to the master and slave.

 Slave Reverse Run Specifications
The direction of the output rotation speed of the slave is dependent on the polarity of the
frequency reference voltage that was input. It is not dependent on the direction of the Run
command (Forward/Reverse).
The direction of the output frequency is as follows.
If the input frequency reference signal is + (positive), the output frequency is positive.
If the input frequency reference signal is - (negative), the output frequency is negative.
* Excluding Auto-Tuning, Jog Operation, and LOCAL Mode.
