communication error
E70 This error is displayed, disconnection occurs when timeout is
occurred, while the inverter is operating with CANopen. (Trip
is caused by P045 setting)
2 External trip E12 This error is displayed, when Halt is set to 1 toward control
word(Index:6040h) in BIT8(Halt).
With regard to the other errors except table above, refer to Inverter instruction manual chapter 4
Explanation of function.
