(d) Feed current value/Roller peripheral velocity register (D0+20n, D1+20n)
....................................................................... Data sent from PCPU to SCPU
1) The target address which is output to the servo amplifier is stored at this
register. The target address is based on the command address
calculated from the mechanical system program settings.
2) A stroke range check occurs at this feed current value data.
3) Roller peripheral velocity is stored.
The storage range for the peripheral velocity at this register is as shown
below.
Setting System-of-Units Storage Range Actual Roller Peripheral Velocity
mm 0.01 to 6000000.00 mm/min
inch
1 to 600000000
0.001 to 600000.000 inch/min
(e) Real current value register (D2+20n, D3+20n)
....................................................................... Data sent from PCPU to SCPU
1) The current value obtained from real travel (feed current value minus the
deviation counter's droop pulse count) is stored at this register.
2) When a STOP status is in effect, the current feed value is equal to the
real current value.
(f) Deviation counter value register(D4+20n, D5+20n)
....................................................................... Data sent from PCPU to SCPU
The difference between the feed current value and the real current value is
stored at this register.
(g) Minor error code register(D6+20n)................ Data sent from PCPU to SCPU
1) When a minor error occurs, the corresponding error code is stored at this
register.
Each time a subsequent error occurs, the stored error code is replaced
by the new error code.
2) Minor error codes are cleared by executing an error reset (M3207+20n).
(h) Major error code register(D7+20n)................ Data sent from PCPU to SCPU
1) When a major error occurs, the corresponding error code is stored at this
register.
Each time a subsequent error occurs, the stored error code is replaced
by the new error code.
2) Major error codes are cleared by executing an error reset (M3207+20n).
(i) Servo error code register(D8+20n)................ Data sent from PCPU to SCPU
1) When a servo error occurs, the corresponding error code is stored at this
register.
Each time a subsequent error occurs, the stored error code is replaced
by the new error code.
2) When a servo error occurs, the system returns to the REAL mode.
(j) Torque limit value register(D14+20n)............ Data sent from PCPU to SCPU
The designated servo torque limit value is stored at this register.
A torque limit value of "300%" is stored here when the servo power is
switched ON, and at the leading edge of the PLC READY (M2000) signal.
