E50
Coefficient for Speed Indication
This function code sets a coefficient to be used for setting the constant rate of
feeding time, load shaft speed or line speed and for displaying its output status.
Const.
Rate
Load Shaft Speed (rpm) = (E50: Coeff. for Speed Indication) ⌠ Frequency (Hz)
Line Speed (m/min)= (E50: Coeff. for Speed Indication) ⌠ Frequency (Hz)
Where, Freq. is the set frequency if each expression is for one of the set data for
the constant rate of feeding time, load shaft speed, or line speed; it is the output
frequency if each expression is for the output status monitor.
C21
Timer Operation
Enables or disables timer operation. If it is enabled, entering a run command will
run the inverter to drive the motor for the period preset to the timer.
An example of timer operation
Setting up the timer conditions beforehand
- Set C21 to 1 to enable timer operation.
- To display the timer count on the LED monitor, set function code E43 (LED
monitor) to 13 (Timer count).
- Set up the frequency for the timer operation using the built-in potentiometer or
the
switch it to the speed monitor and then set the frequency for the timer opera-
tion.
Timer operation (by giving a run command with the
1) Use the
current count displayed on the LED monitor. Note that the timer count is ex-
pressed as integers.
2) Press the
moment the timer finishes the countdown, the inverter stops running the motor
even if the
timer count is not displayed on the LED monitor.)
3) After the inverter decelerates the motor to a stop, the timer count on the LED
monitor will flash.
