5.1 Explanation of monitor signals
Description
The position within one-revolution of the load-side encoder is displayed.
When an incremental type linear encoder is used for the load-side
encoder, the Z-phase counter of the load-side encoder is displayed in
units of encoder pulses.
When an absolute position type linear encoder is used for the load-side
encoder, the encoder absolute position is displayed.
When an incremental or absolute position type linear encoder is used as
the load-side encoder, "0" is displayed. When a rotary encoder is used as
the load-side encoder, the multi-revolution counter value of the encoder is
displayed.
The thermistor temperature is displayed for the servo motor with a
thermistor.
For the servo motors without a thermistor, "9999" is displayed.
For the servo motor with a thermistor, refer to the user's manual for the
servo motor being used.
The feedback pulses from the servo motor encoder are counted and
displayed. (Servo motor encoder unit)
The servo motor electrical angle is displayed.
For the linear servo motor control mode, the value of manufacturer setting
is displayed.
The position deviation between the servo motor-side and load-side is
displayed.
This function can be used for fully closed loop control.
The number of pulses is displayed in the load-side encoder unit.
The speed deviation between the servo motor-side and load-side is
displayed.
This function can be used for fully closed loop control.
The internal temperature detected by the encoder is displayed.
The period of time (settling time) from the completion of the command to
INP (In-position) on is displayed.
The frequency at the time of oscillation detection is displayed.
The number of times the tough drive function has activated is displayed.
The unit power consumption is displayed. The positive value is displayed
in power running. The negative value is displayed in regeneration.
The unit total power consumption is displayed.
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 command speed to be used for speed control is displayed as the
command output of the analog monitor.
The target torque value of the torque command in the torque mode is
displayed. "0" is displayed in the position mode and velocity mode.
The speed limit value in the torque 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.
