6.7 Operation example
The following three operation examples explain the operation of parameter section and
quantity of state.
The quantity of state operation: this part is read only:
The value for “
d-A1
”quantity of sate in “
d-
”of servo drive shows 8. The unit is mV.
When it reads the quantity of state as “speed analog command voltage” through communication
interface, the value is 8. The unit is mV.
Operation for parameter: this part is read-write:
The drive parameter P006
（
the first speed circulation integral time constant
）
shows 20.0. The
unit is ms. Read parameter P006 through communication interface. The value is 20.0. The
precision of this parameter is accurate to the place after the decimal point. It is magnified ten
times when it is read out.
The drive parameter P007 （ the first torque filtering time constant ） shows 1.00. The unit is
ms. The value of parameter P007 modified through communication interface is 2.00. The value
written in is 200. The precision of this parameter is accurate to the second place after decimal
point. It needs to be magnified 100 times when it is written in. If parameter 2 is written directly,
the parameter P007 of drive shows 0.02.
Write the value of state quantity in parameter:
In the speed control mode, the external input analog value is 0. The value of
“
d-A1
”quantity of state in drive“
d-
”is zero bias of analog. It can be read out through
communication interface, and written into the parameter P047 of drive to eliminate zero bias.
The value of state quantity is interger. The value of parameter P0-47 accurates to the place after
decimal point. When read out, the value is intrgral value without magnify. While written in, it
needs to be magnified ten times before written in.
In the instruction of above example, the “
d-A1
”of drive “
d-
”shows 8. The unit is mV.
This state quantity is read as “8”. “80” should be written into parameter P047.
