the servo drive used is ON. For example, the group number assigned to the parameter
P1-44 is 1, the parameter number assigned to it is 44, and the parameter is a 32-bit
parameter.
4. If a parameter in the servo drive can be set only when the servo drive is OFF, the users
have to set the servo drive to OFF. If there is no such limitation, the step can be
skipped.
5. The users have to set a parameter position in the servo drive by means of SR1078
(SR1178, SR1278...). If they want to use P1-44, the value of the high byte in SR1078
(SR1178, SR1278...) will be 16#01, and value of the low byte in SR1078 (SR1178,
SR1278...) will be 16#2C, that is, the value in SR1078 (SR1178, SR1278...) will be
16#012C.
6. The users have to set the value which will be written into a servo drive by means of
(SR1077, SR1076) ((SR1177, SR1176), (SR1277, SR1276)...).
7. The users have to set bit 11~bit 8 in SR1072 (SR1172, SR1272...). If the value of bit
11~bit 8 in SR1072 (SR1172, SR1272...) is 1, the value written into the servo drive will
be a 16-bit value. If the value of bit 11~bit 8 in SR1072 (SR1172, SR1272...) is 2, the
value written into the servo drive will be a 32-bit value. For example, the parameter
P1-44 is a 32-bit parameter, and therefore the bit 11~bit 8 in SR1072 (SR1172,
SR1272...) must be 2.
8. The users can check whether the writing of a value is correct by means of bit 11~bit 8 in
SR1073 (SR1173, SR1273...). If an error occurs, an error code will be stored in
(SR1077, SR1076) ((SR1177, SR1176), (SR1277, SR1276)...). If the writing of a value
is successful, the value of bit 11~bit8 in SR1073 (SR1173, SR1273...) will be 0.
9. The users can write a value into another servo drive or read a value from another servo
drive only after the setting of the servo used is complete, or an error occurs in the servo
used.
 Using a motion control function block
Users can write a value into a servo drive by means of the motion control function block
T_DMCServoWrite.
Please refer to chapter 5 for more information about the input pins and the output pins
in the motion control function block T_DMCServoWrite.
 Steps of reading a value from a servo drive
 Using special data registers
1. Users have to make sure of the node ID of the servo drive used. If the node ID of the
servo drive used is 1, the first axis will be used. If the node ID of the servo drive used is
2, the second axis will be used. If the node ID of the servo drive used is
3/4/5/6/7/8/9/10/11/12, the 3
one axis can be selected at a time.
2. After the users refer to the description of a parameter, they can know the group number
assigned to the parameter, and the parameter number assigned to the parameter. For
example, the group number assigned to the parameter P1-44 is 1, and the parameter
number assigned to it is 44.
3. The users have to set a parameter position in the servo drive by means of SR1078
(SR1178, SR1278...). If they want to use P1-44, the value of the high byte in SR1078
(SR1178, SR1278...) will be 16#01, and value of the low byte in SR1078 (SR1178,
SR1278...) will be 16#2C, that is, the value in SR1078 (SR1178, SR1278...) will be
