10.6 Alarm and Warning Codes for Inverter
10.6.2 V1000
10-68
*1. You can monitor in the following cases.
• When the Inverter Drive Control command is executed when bit 7 (Warning code) of Input Data Option Selec-
tion (OW0D) is ON
• When the Inverter I/O Control subcommand is executed when bit 7 (Warning code) of Auxiliary Input Data
Option Selection (OW0F) is ON
*2. You can monitor the current warning codes when the Alarm Monitor or Alarm History Monitor command is exe-
cuted.
