■ H5-05: Communication Fault Detection Selection
Enables or disabled the communication error (CE) detection for MEMOBUS/Modbus communications.
Setting 0: Disabled
No communication error detection. The drive continues operation.
Setting 1: Enabled
If the drive does not receive data from the master for longer than the time set to H5-09, then a CE fault will be triggered
and the drive will operate as determined by parameter H5-04.
■ H5-06: Drive Transmit Wait Time
Sets the time the drive waits after receiving data from a master before responding.
