3.2 Switch setting and display of the servo amplifier
Regenerative load
ratio
%
The ratio of regenerative power to
permissible regenerative power is
displayed in %.
Effective load ratio
%
The continuous effective load
current is displayed.
The effective value in the past 15 s
is displayed in relation to the rated
current (= 100 %).
Peak load ratio
%
The maximum generated torque is
displayed.
The highest value in the past 15 s is
displayed relative to the rated
torque as 100 %.
Instantaneous
torque
%
The instantaneous torque is
displayed.
The rated torque is displayed as
100 %. The value of the generated
torque is displayed in real time.
Position within one-
revolution (1 pulse
unit)
pulse
The position within one-revolution is
displayed in the encoder pulse unit.
The values in excess of ±99999 can
be counted. However, the counter
shows only the lower five digits of
the actual value because the servo
amplifier display is five digits.
When the servo motor rotates in the
CCW direction, the value is added.
Position within one-
revolution (1000
pulses unit)
1000
pulses
The position within one-revolution is
displayed by increments of 1000
pulses unit of the encoder.
When the servo motor rotates in the
CCW direction, the value is added.
ABS counter
rev
The travel distance from the home
position is displayed as multi-
revolution counter value of the
absolution position encoder in the
absolution position detection
system.
Load to motor
inertia ratio
Multiplier
The estimated ratio of the load
inertia moment to the servo motor
inertia moment is displayed.
Bus voltage
V
The voltage of main circuit
converter (between P+ and N-) is
displayed.
Internal temperature
of encoder
°C
The internal temperature detected
by the encoder is displayed.
If the internal temperature of
encoder cannot be obtained, such
case as the linear servo motor or
others, "9999" is displayed.
Settling time
ms
The settling time is displayed. When
the settling time exceeds 1000 ms,
"1000" is displayed.
Oscillation detection
frequency
Hz
The frequency at the time of
oscillation detection is displayed.
