4.20 Disconnection/incorrect wiring detection function
Setting method [G] [B]
■200 V class 1-axis servo amplifiers with a capacity of 2.0 kW or less
When [Pr. PC20.4 Input open-phase detection selection] is set to "0" (automatic), the input open-phase detection function is
disabled.
The input open-phase detection function is enabled by setting [Pr. PC20.4] to "1" (warning enabled) or "2" (alarm enabled). If
"1" (warning enabled) is set, [AL. 1E9 Open-phase warning] will be output when the input open phase occurs. To generate
[AL. 139 Open-phase error] when an open phase occurs, set [Pr. PC20.4] to "2" (alarm enabled).
■200 V class 1-axis servo amplifiers with a capacity of more than 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] will be output when an input open phase occurs. To generate
[AL. 139 Open-phase error] when an open phase occurs, set [Pr. PC20.4] to "2" (alarm enabled).
■200 V class multi-axis servo amplifiers with a capacity of 0.75 kW or less
When [Pr. PC20.4 Input open-phase detection selection] is set to "0" (automatic), the input open-phase detection function is
disabled.
The input open-phase detection function is enabled by setting [Pr. PC20.4] to "1" (warning enabled) or "2" (alarm enabled). If
"1" (warning enabled) is set, [AL. 1E9 Open-phase warning] will be output when the input open phase occurs. To generate
[AL. 139 Open-phase error] when an open phase occurs, set [Pr. PC20.4] to "2" (alarm enabled).
■200 V class multi-axis servo amplifiers with a capacity of more than 0.75 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] will be output when an input open phase occurs. To generate
[AL. 139 Open-phase error] when an open phase occurs, set [Pr. PC20.4] to "2" (alarm enabled).
■400 V class 1-axis servo amplifiers
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] will be output when an input open phase occurs. To generate
[AL. 139 Open-phase error] when an open phase occurs, set [Pr. PC20.4] to "2" (alarm enabled).
