(7) Connection between the QD77GF and servo amplifier with CC-Link
IE Field Network
(a) The servo parameters can be set on the QD77GF side to write or read
them to/from the servo amplifier using the CC-Link IE Field Network in MR
Configurator2.
(b) The actual current value and error description contained in the servo can
be checked by the buffer memory of the QD77GF.
(c) The communication between the MR Configurator2 and servo amplifiers is
possible via the PLC CPU.
(Note-1): It is available in MR-J4-B-RJ010 communication mode.
(8) Easy application to the absolute position system
(a) The servo amplifier MR-J4-_B_-RJ010 and MR-J4-GF corresponding to
the CC-Link IE Field Network and servo motors correspond to the absolute
position system. It can be realized only at connecting the battery for
absolute position system to the servo amplifier.
(b) Once the HP have been established, the HPR operation is unnecessary at
the system's power supply ON.
(c) With the absolute position system, the data set method HPR is used to
establish the HP. The wiring of proximity dog, etc. is unnecessary.
(d) When the setting unit is "degree", the absolute position system with
unlimited length fed can be configured.
