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.
Index Sub Index Data Type Access Data type Description
2B01 0 I32 rw Cumulative feedback pulses Feedback pulses from the servo motor encoder are counted
and displayed.
Writing "0000 1EA5h" to this object clears the cumulative
feedback pulses.
2B02 0 I32 ro Servo motor speed The servo motor speed is displayed.
2B03 0 I32 ro Droop pulses The number of droop pulses in the deviation counter is
displayed. The number of pulses displayed is in the encoder
pulse unit.
2B04 0 I32 ro Cumulative command pulses Position command input pulses are counted and displayed.
2B05 0 I32 ro Command pulse frequency The frequency of position command input pulses is counted and
displayed.
2B08 0 U16 ro Regenerative load ratio The ratio of regenerative power to permissible regenerative
power is displayed in %.
2B09 0 U16 ro Effective load ratio The continuous effective load current is displayed.
The effective value is displayed considering a rated current as
100%.
2B0A 0 U16 ro Peak load ratio The maximum torque generated is displayed.
The highest value in the past 15 s is displayed, with the rated
torque being 100%.
2B0B 0 I16 ro Instantaneous torque The instantaneous torque is displayed.
The value of torque being occurred is displayed in real time
considering a rated torque as 100%.
2B0C 0 I32 ro Within one-revolution position Position within one revolution is displayed in encoder pulses.
2B0D 0 I32 ro ABS counter 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.
2B0E 0 U16 ro Load to motor inertia ratio The set ratio of the load inertia moment to the servo motor shaft
inertia moment is displayed.
2B0F 0 U16 ro Bus voltage The voltage of main circuit converter (between P+ and N-) is
displayed.
2B10 0 I32 ro Load side encoder cumulative
feedback pulses Feedback pulses from the load-side encoder are counted and
displayed.
2B11 0 I32 ro Load side encoder droop pulses Droop pulses of the deviation counter between a load-side
position and a command are displayed.
2B12 0 I32 ro Load side encoder information 1 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.
2B13 0 I32 ro Load side encoder information 2 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.
