RTC function can not run normally when:
- When multi-function terminal (03-00~03-05) is set to the fire mode.
- When KEB function is enabled
Source of main frequency of RTC function is according to Table 4.4.14 and also can refer to
main and alternative frequency command modes (00-07).
If main run command source selection (00-02) is set to 0~3 (0: keypad, 1: external terminal, 2:
communication control, 3: PLC), refer to Table 4.4.15 for the relationship between main run
command and RTC timer status.
Table 4.4.15 Relationship between main run command and RTC timer status
Main run command
00-02
RTC timer x status Inverter status
0~3 0 Inverter can not run (without run command)
0~3 1 Inverter can not run (without run command)
4 0 Inverter can not run (RTC timer is disabled)
4 1
Inverter runs and rotates depending on the function
of 16-37.
Take an example for RTC timer connecting with different parameters:
The work time on Monday is 6:00 AM to 10:00 PM.
The work time on Tuesday to Friday is 8:00 AM to 8:00 PM.
The work time on Saturday is 8:00 AM to 6:00 PM.
The work time on Sunday is 8:00 AM to 12:00 PM.
Motor runs on weekdays (Mon. to Fri.) at speed 1 and on weekends at speed 2.
