• Drive running – (RUN2)

(Function code data = 35)

This signal is turned ON when the main switching
circuit (Insulated Gate Bipolar Transistor (IGBT) gates) is
activated; it is OFF when it is not activated.
Related item: Refer to “drive running (Speed > 0)
– (RUN).”
• Overload prevention control – (OLP)

(Function code data = 36)

This signal is turned ON when the overload prevention
facility is activated if the frequency drop rate comes
to be the setting specified by function code H70. The
minimum ON-duration is 100 ms.
REFERENCE: For details of the overload prevention
control, refer to the descriptions of function code H70.
• Current detection – (ID)

(Function code data = 37)

This signal is turned ON when the output current
exceeds the operation level specified by function code
E34 and stays in this status for the duration specified
by function code E35 (on delay timer). The minimum
ON-duration is 100 ms.
NOTE: Function codes E34 and E35 are effective not
only for current detection (ID), but often also for overload
early warning (OL) and low level current detection (IDL).
• Low level current detection – (IDL)

(Function code data = 41)

This signal is turned ON when the output current drops
below the operation level specified by function code
E34 and stays in this status for the duration specified by
function code E35 (on delay timer). The minimum turning
ON time is 100 ms.
NOTE: Function codes E34 and E35 are effective not
only for the low level current detection (IDL), but often
also for the overload early warning (OL) and current
detection (ID).
• Alarm relay contact output (for any fault) – (ALM)

(Function code data = 99)

This signal is turned ON if the protection facility is
activated so that the drive enters Alarm mode.

E50 Coefficient for Speed Indication

This function code sets a coefficient to be used for
setting the constant feeding rate time, load shaft speed
or line speed and for displaying its output status.

Where, Freq. is the set frequency if each expression is
for one of the set data for the constant feeding rate time,
load shaft speed, or line speed; it is the output frequen-
cy if each expression is for the output status monitor.
NOTE: PID display coefficients A and B (E40 and E41)
are the exclusive conversion factors to equate an indi-
cated value with the process command and feedback
values in PID control.

C21

Timer Operation

Enables or disables timer operation. If it is enabled,
entering a run command will make the drive run the
motor for the period preset in 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  /  keys. If the LED
displays the timer count, press the   key to switch it to
the speed monitor and then set the frequency for the
timer operation.
Timer operation (by giving a run command with the

key):
1) Use the or key to set the timer count (in sec-

onds) while monitoring the current count displayed
on the LED monitor. Note that the timer count is
expressed as integers.

2) Press the key to run the motor, and the timer will

start to count down. The moment the timer finishes
the countdown, the drive stops running the motor
even if the key is not pressed. (Timer operation is
possible even when the timer count is not displayed
on the LED monitor.)

3) After the drive decelerates the motor to a stop, the

timer count on the LED monitor will flash.
