(5) Servo parameter
(a) Control of servo parameters
Parameters of VCII series/VPH series are not controlled by Simple
Motion module. Therefore, even though the parameter of VCII
series/VPH series is changed during the communication between Simple
Motion module and VCII series/VPH series, it does not reflect to the
buffer memory of the Simple Motion module.
(b) Servo parameter change request
Change request of servo parameter ("
Cd.130
Servo parameter write
request
" to "
Cd.132
Change data
") can be executed. However, the servo
parameter of VCII series/VPH series is controlled in a unit of 2 words, so
that it is necessary to set "2: 2 words write request" in "
Cd.130
Servo
parameter write request
" for executing the parameter write. If 1 word write
is executed to VCII series/VPH series, the parameter write is failure, and
"3" is stored in "
Cd.130
Servo parameter write request
".
When the servo parameter of VCII series/VPH series is changed by the
servo parameter change request, the parameter value after changing the
servo parameter cannot be confirmed using VCII/VPH data editing
software. Also, when the power of VCII series/VPH series is turned OFF,
the parameter changed by the servo parameter change request
becomes invalid, and the value written by VCII/VPH data editing software
becomes valid.
(6) Optional data monitor
The following table shows data types that can be set.
Data type Unit
Effective load ratio [%]
Regenerative load ratio [%]
Peak load ratio [%]
Model loop gain [rad/s]
Main circuit bus voltage
(Note)
[V]
Encoder multiple revolution counter [rev]
Position feedback (Used point: 2 words) [PLS]
Encoder position within one revolution (Used point: 2 words) [PLS]
(Note): It can be monitored when using VPH series.
(7) Gain switching command, PI-PID switching request, Semi/Fully closed loop
switching request
Gain switching command and PI-PID switching request are available.
Semi/fully closed loop switching request becomes invalid.
(8) Driver communication
The driver communication is not supported. If the driver communication is
set in a servo parameter, the error "Driver communication setting error"
(error code: 975) will occur when the power is turned ON, and any servo
amplifiers including VCII series/VPH series cannot be connected.
