Appendix 12
When you use a linear servo motor, replace the following left words to the right words.
CCW direction  Positive direction
CW direction  Negative direction
Torque  Thrust
Servo cyclic transmission function
The servo cyclic transmission function is used to monitor data in the servo amplifier with the servo system controller. In the
servo cyclic transmission function, data types of registered monitor objects can be set. Setting Index, Sub Index, and Data
Type for 2B01h allows you to write to 2B01h.
For details of usage, the unit of data types, and others, refer to RD77GF Simple Motion Module User's Manual.

Description
Feedback pulses from the servo motor encoder are counted
and displayed.
Writing "0000 1EA5h" to this object clears the cumulative
feedback pulses.
The servo motor speed is displayed.
The number of droop pulses in the deviation counter is
displayed. The number of pulses displayed is in the encoder
pulse unit.
Position command input pulses are counted and displayed.
The frequency of position command input pulses is counted and
displayed.
The ratio of regenerative power to permissible regenerative
power is displayed in %.
The continuous effective load current is displayed.
The effective value is displayed considering a rated current as
100%.
The maximum torque generated is displayed.
The highest value in the past 15 s is displayed, with the rated
torque being 100%.
The instantaneous torque is displayed.
The value of torque being occurred is displayed in real time
considering a rated torque as 100%.
Position within one revolution is displayed in encoder pulses.
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.
The set ratio of the load inertia moment to the servo motor shaft
inertia moment is displayed.
The voltage of main circuit converter (between P+ and N-) is
displayed.
Feedback pulses from the load-side encoder are counted and
displayed.
Droop pulses of the deviation counter between a load-side
position and a command are 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 by 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 type linear encoder is used for the load-
side encoder, the display shows 0.
When an absolute position type linear encoder is used for the
load-side 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.
