Communication Fault (CE) Response Selection – H5-04. Select the drive operation method when a communication fault (CE)
occurs. See parameter H5-05 also.
Table 1.4 Communication Fault Response Selection – Parameter H5-04
Value Description
0 Ramp to Stop (Fault)
1 Coast to Stop (Fault)
2 Fast Stop (Fault)
3 Alarm Only (Alarm) (Default Setting)
4 Run at D1-04 frequency
Communication Fault (CE) Detection Selection – H5-05. Selects whether the communication fault (CE) is monitored. Please note
that either B1-01 or B1-02 must also be set to a 2 (Serial Communication) for fault monitoring to occur. If the CE fault is enabled, the
G7 will flash CALL on the keypad after power up until a message is received. The drive will trip and respond according to H5-04 if
communication is lost (a message is not received) for more than 2 seconds after successful communication has been initiated.
Table 1.5 Communication Fault Detection Selection – Parameter H5-05
Value Description
0 Disabled (Default Setting)
1 Enabled
Serial Communication Send Delay – H5-06. A delay can be inserted before the G7 drive responds to a command message. This
allows for slower communication devices to switch their transceiver state in order to get ready to receive a message. A value of 5 ~ 65
ms can be inserted, with 5 ms being the default.
RTS Control – H5-07. This parameter determines whether RTS is continually asserted (disabled) or asserted only during send
(enabled). RTS must be enabled for use with RS-485 2-wire communication.
Table 1.6 RTS Control – Parameter H5-07
Value Description
0 Disable (always ON) (Default Setting)
1 Enable (ON only during send) (Use this setting for RS-485 2-wire systems)
