5.1 Explanation of monitor signals
Description
In the profile position mode (pp) and point table mode (pt), the command current position
with the machine home position set as "0" is displayed.
This indicates the position command from the controller in the cyclic synchronous position
mode (csp).
In the profile position mode (pp) and point table mode (pt), the selected profile position or
the remaining distance to the command position of the point table is displayed. In other
control modes, "0" is displayed.
In the positioning mode (point table method), the selected point table number is displayed.
In other control modes, "0" is displayed.
The selected number is displayed during a temporary stop or in JOG operation mode.
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 and positioning 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, positioning 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, positioning 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.
This indicates the cumulative number of errors during communication with the load side
encoder.
The control mode number of the servo amplifier indicated in [Modes of operation display
(Obj. 6061h)] is displayed.
Droop pulses of the deviation counter between a servo motor-side position and a model
position are displayed.
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
is displayed 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 %.
The current position of the servo motor is displayed.
