Name
Display the maintenance timer (cumulative
energization time) in 1000h increments.
Parameter write is not enabled.
0 to 999
When the maintenance timer has elapsed
the time set in H2, the Y95 signal is output.
Assign the Y95 signal with Pr. 64 or Pr. 65.
0 to 999, ---
The average value of the output current
during constant speed operation and the
maintenance timer value are output to the
current average value monitor signal (Y93).
Y93 signal is output for 20s as 1 cycle in
order of start pulse for 1s(Hi), output
current average value for 0.5 to 9s (Low),
maintenance timer value for 2 to 9s (Hi),
and end signal (Low).
Assign the Y93 signal to the RUN terminal
using Pr. 64.
Set the time (0.1 to 1s) taken to calculate
average value of the output current during
constant operation in H3.
Set the time (0 to 20s) for not outputting
the Y93 signal to invalidate retrieving of
output current value in the transient state
right after the speed is changed from
acceleration/deceleration to constant
speed in H4.
Set the current value (0.1 to 999A) when
outputting the average value of output
current as a low pulse shape for 5s in H5.
Name
You can select whether to use system to
detect the motor speed (speed search
system) at the time of restart after
instantaneous power failure or not
0: with speed search, 1: without speed
search, 10: with speed search at starting
Protect the second motor from overheat.
Set the rated current value of the second
motor.
Made valid when the RT signal turns on.
Refer to Pr. 9 for its function.
