Function:
Enter the I value. When the motor current exceeds this limit, the display reads
HIGH
outputs can be programmed to produce a status signal on terminal 27 or 29 (FC 302 only) and on relay output
01 or 02 (FC 302 only). Refer to the drawing in this section.
Function:
Enter the n value. When the motor speed exceeds this limit, the display reads
LOW
can be programmed to produce a status signal on terminal 27 or 29 (FC 302 only) and on relay output 01 or 02
(FC 302 only).
Function:
Enter the n value. When the motor speed exceeds this limit, the display reads
HIGH
can be programmed to produce a status signal on terminal 27 or 29 (FC 302 only) and on relay output 01 or 02
(FC 302 only). Programme the upper signal limit of the motor speed, n
the frequency converter. Refer to the drawing in this section.
Function:
Enter the lower reference limit. When the actual reference falls below this limit, the display indicates
The signal outputs can be programmed to produce a status signal on terminal 27 or 29 (FC 302 only) and on
relay output 01 or 02 (FC 302 only).
Function:
Enter the upper reference limit. When the actual reference exceeds this limit, the display reads Ref High. The
signal outputs can be programmed to produce a status signal on terminal 27 or 29 (FC 302 only) and on relay
output 01 or 02 (FC 302 only).
Function:
Enter the lower feedback limit. When the feedback falls below this limit, the display reads Feedb Low. The signal
outputs can be programmed to produce a status signal on terminal 27 or 29 (FC 302 only) and on relay output
01 or 02 (FC 302 only).
Function:
Enter the upper feedback limit. When the feedback exceeds this limit, the display reads Feedb High. The signal
outputs can be programmed to produce a status signal on terminal 27 or 29 (FC 302 only) and on relay output
01 or 02 (FC 302 only).
Select [Off] for no missing motor phase alarm. However the [On] setting is strongly recommended to avoid
motor damage.
Select [On] to display an alarm in the event of a missing motor phase.
