Function Group:
Enabling External Input for X-Y Axis
Number:
D1875, D1955
Explanations:
1. When high byte of D1875 / D1955 = H’01, external input is enabled. When high byte of D1875 / D1955 = H’00
external input is disabled.
2. The low byte of D1875 and D1955 indicates the starting number of 4 consecutive external inputs (X), e.g., H’00
indicates X0 ~ X3 is to be enabled corresponding to JOG+, JOG-, MPG and ZRN.
3. Example: D1875 and D1955 = H’0110 refers to JOG+, JOG-, MPG and ZRN is enabled on X10 ~ X13.
Function Group:
Close-loop PID control (not supported by DVP-10PM)
Number:
D1877, D1878, D1880, D1882, D1888
Explanations:
1.
D1877 is the register for setting up close-loop PID control. The user can enable and select the feedback source of
PID control system.
Value of D1877
Feedback source
1 C200
2 C204
3
Current value (D1848
、
D1928
、
D2008)
Other
Disable close-loop PID control function
2. D1878, D1879: Set value (target value) of PID control. PID control system adjusts the output value to the set
value by referencing the value from feedback source.
3. D1880,
D1881:
K
P
value, i.e. proportional gain for close-loop PID control.
4. D1882, D1883: K
I
value, i.e. integral gain for close-loop PID control.
5. D1888, D1889: The tolerable range for error(difference) between input and output value. The value set up in
D1888 will limit the accumulated error within the tolerable range.
