Setting method [G] [WG]
■When the 1-axis servo amplifier capacity is 2.0 [kW] or less
If "0" (automatic) is set in [Pr. PC20.4 Input open phase detection selection], the input open-phase detection function will be
disabled.
The input open-phase detection function is enabled by setting [Pr. PC20.4 Input open phase detection selection] to "1"
(warning enabled) or "2" (alarm enabled). If "1" (warning enabled) is set, [AL. 1E9 Open phase warning] will be outputted
when the input open phase occurs. To generate [AL. 139 Open phase error] when an open phase occurs, set [Pr. PC20.4
Input open phase detection selection] to "2" (alarm enabled).
■When the 1-axis servo amplifier capacity exceeds 2.0 [kW]
When [Pr. PC20.4 Input open phase detection selection] is set to "0" (automatic), the input open-phase detection function is
enabled. If "0" (automatic) is set, [AL. 1E9 Open phase warning] is outputted when the input open phase occurs. To generate
[AL. 139 Open phase error] when an open phase occurs, set [Pr. PC20.4 Input open phase detection selection] to "2" (alarm
enabled).
■In the case of MR-J5W_-G_
When [Pr. PC20.4 Input open phase detection selection] is set to "0" (automatic), the input open-phase detection function is
enabled. If "0" (automatic) is set, [AL. 1E9 Open phase warning] is outputted when the input open phase occurs. To generate
[AL. 139 Open phase error] when an open phase occurs, set [Pr. PC20.4 Input open phase detection selection] to "2" (alarm
enabled).

■When the 1-axis servo amplifier capacity is 2.0 [kW] or less
If "0" (automatic) is set in [Pr. PC27.4 Input open phase detection selection], the input open-phase detection function will be
disabled.
The input open-phase detection function is enabled by setting [Pr. PC27.4 Input open phase detection selection] to "1"
(warning enabled) or "2" (alarm enabled). If "1" (warning enabled) is set, [AL. 1E9 Open phase warning] will be outputted
when the input open phase occurs. To generate [AL. 139 Open phase error] when an open phase occurs, set [Pr. PC27.4
Input open phase detection selection] to "2" (alarm enabled).
■When the 1-axis servo amplifier capacity exceeds 2.0 [kW]
When [Pr. PC27.4 Input open phase detection selection] is set to "0" (automatic), the input open-phase detection function is
enabled. If "0" (automatic) is set, [AL. 1E9 Open phase warning] is outputted when the input open phase occurs. To generate
[AL. 139 Open phase error] when an open phase occurs, set [Pr. PC27.4 Input open phase detection selection] to "2" (alarm
enabled).
