This alarm is issued if any of the following conditions occur:
1) A value beyond the specifiable range is set in parameter No. 2020 (motor
type).
2) A correct value (111 or –111) is not set in parameter No. 2022 (motor rotation
direction).
3) An incorrect value such as a negative value is set in parameter No. 2023
(number of speed feedback pulses per motor revolution).
4) An incorrect value such as a negative value is set in parameter No. 2024
(number of position feedback pulses per motor revolution).
5) Parameter Nos. 2084 and 2085 (flexible feed gear ratios) are not set.
6) A value beyond a range from 1 to the number of controlled axes, or a value
not successive is set in parameter No. 1023 (servo axis number).
(g) External alarms
A one–byte data, ID No. 55, representing a number from 0 to 255
indicates which external alarm was issued.
The information of ID Nos. 56 to 59 directly indicates alarm
numbers.
For one–byte data, see Section 6.29.3.(1)(b). For the meaning of
each bit, see the external alarm table.
