5.1 Explanation of monitor signals
Description
The margin for the excessive error alarm level is displayed in the encoder pulse unit. The
excessive error alarm occurs at 0 pulses.
The margins for the alarm levels of [AL. 050 Overload 1] and [AL. 051 Overload 2] are
displayed as a percentage.
The overshoot amount during position mode is displayed in units of encoder pulses.
The difference between the necessary torque and the actually required torque (torque
current value) to drive the servo motor is displayed as the torque equivalent to
disturbance.
This indicates the current command applied to the servo motor.
This indicates the speed command being applied to the servo motor.
In the position mode, the speed command calculated from the position command and
command filter is displayed.
The torque command in the torque mode or the target torque value in the continuous
operation to torque control mode is displayed.
"0" is displayed in the position mode and velocity mode.
The speed limit value in the torque mode or continuous operation to torque control mode
is displayed.
"0" is displayed in the position mode and velocity mode.
*1
This indicates the U-phase current value applied to the servo motor in internal units.
*1
This indicates the V-phase current value applied to the servo motor in internal units.
This indicates the cumulative number of errors during communication with the encoder.
The control mode number of the servo amplifier indicated in [Modes of operation display
(Obj. 6061h)] is displayed.
This indicates the position deviation between the model and servo motor.
This indicates the speed command being applied to the servo motor.
The number of droop pulses in the deviation counter is displayed. The number of pulses
displayed is in the command unit.
The value of the U-phase current flowing in the servo motor is displayed in increments of
*2
0.1 % in relation to the rated current as 100 %.
The value of the V-phase current flowing in the servo motor is displayed in increments of
*2
0.1 % in relation to the rated current as 100 %.
The value of the W-phase current flowing in the servo motor is displayed in increments of
*2
0.1 % in relation to the rated current as 100 %.
