Parameter Name Function Data Type
Default
Value
19 Max.Deceleration
The available max. deceleration; (Unit:
unit)
REAL 10000
Parameters 17~19 are used in the specific situation. E.g. The velocity, acceleration and deceleration of
G0 in instruction CNC; the velocity, acceleration and deceleration at which slave enters the state of
meshing with the master axis when Cam in; the velocity, acceleration and deceleration at which slave
follows the master to move when Gear in.
20 Position
The current position of servo drive
(Unit: Pulse)
DINT
21 Velocity
The current speed of servo drive
(Unit: 0.1 rpm)
DINT
22 Torque
The current torque of servo drive
( Permille of the rated torque)
INT
Above three parameters are used for setting DVP10MC11T to adjust PID of servo drive
23 Current
The present current of servo drive
( Permille of the rated current)
INT
24
User defines
parameter
Servo drive parameters customized by
users
“User defines parameter” is the servo drive parameter to be read. Its length is specified according to the
data type of the read parameter.
The byte parameter length is 1; the word parameter length is 2 and double-word parameter length is 4.
The method of calculating sub-index and index of the servo drive parameter is shown below:
Index= Servo drive parameter (Hex) + 2000 (Hex), Sub-index=0
For example: The index of servo drive parameter P6-10:
2000+060A (P6-10 hex.)=260A; sub-index: 0.
Cyclic communication data can be selected by users. The data length selected can not exceed 8 bytes
which can be calculated by computer automatically. The data length of position, speed, torque and
current are 4 bytes, 4 bytes, 2 bytes and 2 bytes respectively. The current value of cyclic communication
data selected by user can be read by the special registers related with axis. See appendix C for more
details.
