ess data loss behavior
When [E8.01] = 0.0 s, the disruption detection function is inactive.
If the interval between the current and next communication commands exceeds
the time defined in [E8.01] 'Communication error detection time', the frequency
converter will reports a communication error code and act as defined in [E8.02]
'Communication error protection mode':
[E8.02] = 0: Freewheeling stop
●
The motor freewheels to stop after the communication timeout no matter the
settings of parameter E0.50 'Stop mode'.
[E8.02] = 1: Keep running
●
The motor continues running at the setting frequency, and warning code 'C-
dr' will be displayed on the operating panel.
[E8.02] = 2: Emergency stop
●
The motor decelerate to stop after the communication timeout no matter the
settings of parameter E0.56 'Emergency stop action', the deceleration time is
E0.57.
E8.03 determines the behavior of the frequency converter when the communica-
tion extension card process data lost:
[E8.03] = 0: Decelerating stop
●
The motor decelerates to stop according to the defined deceleration time
when the communication extension card process data lost.
[E8.03] = 1: Freewheeling stop
●
The motor freewheels to stop after the communication extension card proc-
ess data lost no matter the settings of parameter E0.50 'Stop mode'.
[E8.03] = 2: Keep running without warning
