Display item
This displays the position loop gain.
Position loop gain :
The error of the actual machine position to the command position is
called droop. This error is proportional to command speed value.
(Command units)
This displays the actual rotation speed of motor.
This displays the motor current in terms of continuous current during
stalling.
This displays the current FB ratio to the current limit as a percentage. The
maximum value of the current FB peak sampled after the power was
turned ON is constantly displayed.
This displays the rate of current FB to current limit as a percentage.
The maximum value of the current FB peak sampled in the last two
seconds is constantly displayed.
This is the data used to monitor motor overload.
This is the data used to monitor the resistance over load state when the
resistance regenerative power supply is connected.
This displays the 7-segment LED of the driver.
This displays the alarms and warnings other than the amplifier display.
This displays the position within one rotation of the encoder detector. The
position is displayed as a grid point value as "0", within one rotation in the
range of "0" to "RNG (movement units) × 1000".
This displays the grid space for the zero point return.
