LED monitor (display when stopped)
E44 specifies whether the specified value (data = 0) or the output value (data = 1) will be displayed on the LED
monitor of the keypad when the inverter is stopped. The monitored item depends on the E48 (LED monitor, Speed
monitor item) setting as shown below.

Torque Command Monitor (Polarity selection)
The polarity of calculated torque value in v/f control or the torque command value in vector control is normally + for
driving and – for braking. However in the case of hoisting load, when the motor rotation direction changes from
forward direction to reverse direction, the torque polarity also changes from driving to braking. If it monitors the
torque data by FRENIC-Loader, we cannot take the expected data around zero speed because the polarity
changes. If E49 is set to 0, the torque monitor data becomes + for forward/driving and reverse/braking, - for
forward/braking and reverse/driving. Therefore we can monitor the continuous torque data around zero speed.

0 Torque polarity
(+ for forward/driving and reverse braking, - for forward/braking and reverse/driving)
1 (Factory setting) Plus for driving, Minus for braking
