Feedback pulses from the servo motor encoder are counted and
Pulse F/B pulse displayed.
Pressing the "RESET" key of the parameter unit will be "0".
The servo motor speed or linear servo motor speed is displayed.
Speed F/B r/min "-" is shown for reverse rotation.
It is displayed rounding off 0.1 r/min (0.1 mm/s) unit.
Droop pulses of the deviation counter between a command and servo
motor encoder are displayed.
Droop Pls pulse
"-" is shown for reverse rotation pulses.
The number of pulses displayed is in the encoder pulse unit.
Pulse Cmd pulse
Pulse Frq kpps
Not used with the positioning mode.
Speed Cmd volt
Not used with the positioning mode.
Trq Limit volt
Voltage of TLA (Analog torque limit) voltage is displayed.
The ratio of regenerative power to permissible regenerative power is
Regn Load %
displayed in %.
The continuous effective load current is displayed.
Effc Load %
The effective value in the past 15 s is displayed relative to the rated
current of 100%.
The maximum occurrence torque is displayed.
Peak Load %
The highest value in the past 15 s is displayed relative to the rated
torque of 100%.
The instantaneous torque is displayed.
Instn Trq %
The value of torque being occurred is displayed in real time considering
a rated torque as 100%.
The position within one revolution of the servo motor is displayed by
pulses.
Cyc posit pulse
When the value exceeds the maximum number of pulses, it resets to 0.
When the servo motor rotates in the CCW direction, the value is added.
The travel distance from the home position is displayed as multi-
Abs count rev revolution counter value of the absolution position encoder in the
absolution position detection system.
The estimated ratio of the load inertia moment to the servo motor shaft
Moment Rt
inertia moment is displayed.
P-N Volt volt The voltage of main circuit converter (between P+ and N-) is displayed.
Feedback pulses from the load-side encoder are counted and
Opt plsFB pulse
displayed.
Droop pulses of the deviation counter between a load-side encoder and
Opt Droop pulse
a command are displayed.
When an incremental encoder is used for the load-side encoder, the Z-
phase counter of the load-side encoder is displayed by encoder pulses.
Opt Cycpo pulse
When an absolute position linear encoder is used for the load-side
encoder, the encoder absolute position is displayed.
When an incremental linear encoder is used for the load-side encoder,
the display shows 0.
When an absolute position linear encoder is used for the load-side
Opt Abscn rev
encoder, the display shows 0.
When a rotary encoder is used for the load-side encoder, the display
shows the multi-revolution counter value of the encoder.
