Overview
S1A53838 09/2011 51
By display terminal Control
Control of the motor speed is enabled, if:
z Parameter [Frequency mode sel] (FMOd) is set to 3.
z Alternate speed reference source parameter [Remote spd ref 2] (F207) has not been enabled.
By Serial communication control
Serial communication control (Modbus, Metasys N2, Apogee FLN, BACnet or LonWorks) of the motor speed is
enabled, if:
z Parameter [Com channel choice] (F807) is set to 0 (only for Modbus on RJ45 port),
z Parameter [Com channel choice] (F807) is set to 1,
z Parameter [Frequency mode sel] (FMOd) is set to 4.
z Alternate speed reference source parameter [Remote spd ref 2] (F207) has not been enabled.
By +/- Motor Speed Control
+/- Motor speed control is enabled, if:
z Parameter [Frequency mode sel] (FMOd) is set to 5,
z Alternate speed reference source parameter [Remote spd ref 2] (F207) has not been enabled.
Selecting Motor Rotation Direction in Remote Mode
The diagram on page 46
illustrates the motor rotation command source when the drive is in remote mode.
With Logic Input Terminals
Use the logic input terminals F, R, RES, or VIA to select motor rotation direction if parameter [Command mode
sel] (CMOd) is set to 0 (factory setting).
With the embedded display terminal or graphic display option
Motor rotation direction can be set by pressing the display terminal UP and ENT keys if:
z Parameter [Command mode sel] (CMOd) is set to 1,
z Serial communication control has not been established.
z Parameter [Local mot. direction] (Fr) is set to either 2 or 3.
With Serial Communication
The drive responds to commands sent over the serial communication link (Modbus, Metasys N2, Apogee FLN,
BACnet or LonWorks) if Parameter [Command mode sel] (CMOd) is set to 2.
Resetting drive detected faults in Remote Mode
The diagram on page 46
illustrates the clear detected fault command source when the drive is in remote mode.
It is not possible to clear a drive detected fault if the cause of the detected fault persists. Be certain to diagnose
and rectify the cause of the detected fault before attempting to reset the drive.
See Automatically Resettable detected faults on page 124
for a list of detected faults that can be cleared in
remote mode.
With the Logic Input Terminals
Use the logic input terminals F, R, RES, or VIA to clear a drive detected fault if parameter [Command mode sel]
(CMOd) is set to 0 (factory setting).
With the graphic/embeded display terminals
The STOP key can be used to clear a drive detected fault if parameter [Command mode sel] (CMOd) is set to 1.
To clear a drive detected fault, press the STOP key. If it is possible to reset the drive, it will display CLr. To
clear the detected fault, press the STOP key a second time.
If the cause of the interruption is still present, the CLr display will not appear. Diagnose and clear the detected
fault before attempting to reset the drive.
The use of the STOP key as a clear detected fault can be managed by parameter [HMI reset button]
(F735).
