Description
When "1" is set in RYC, the specified monitored data is set to the lower 8 bits of the
monitor code (RWw0).
When "0" is set to the upper 8 bits of the monitor code (RWw0), the current output
frequency is always set. When a value other than "0" is set to the upper 8 bits of the
monitor code (RWw0) while "1" is set in RYC, the monitor data specified by the upper
8 bits of the monitor code (RWw0) is set.
When "1" is set in RYD or RYE, the reply code for the frequency setting command is
set. When "1" is set in RYF, the reply code corresponding to the instruction code RWw2
is set. The value "0" is set for a normal reply and any digit other than "0" is set for data
fault, mode error, etc. (Refer to page 5-815.)
Lower 8 bits of RWr2
When "1" is set in RYD or RYE, the reply code for the frequency setting command
(torque command / torque limit) is set. (Refer to page 5-815.)
Upper 8 bits of RWr2
When "1" is set in RYF, the reply code corresponding to the instruction code RWw2 is
set. (Refer to page 5-815.)
For a normal reply, the reply data to the instruction specified by the instruction code
is set.
When "1" is set in RYC, the monitored data specified by the monitor code (RWw4 to 7)
is saved.
The fault data of faults history No. specified by RWw8 is stored in the lower 8bits.
Faults history No. specified is echo backed to the upper 8 bits.
Output frequency of the faults history No. specified in RWw8 is stored.
Output current of the faults history No. specified in RWw8 is stored.
Output voltage of the faults history No. specified in RWw8 is stored.
Energization time of the faults history No. specified in RWw8 is stored.
When "1" is set in RYF, the reply codes corresponding to the instruction code RWw10,
12, 14, 16, and 18 are set. The value "0" is set for a normal reply and other than "0" is
set for data fault, mode error, etc. (Refer to page 5-815.)
For a normal reply, the reply data to the instruction specified by the instruction code
is set.
