Name
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 bit 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
System to detect the motor speed at the
time of restart after instantaneous power
failure
You can select whether to use (speed
search system) 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.
0 to 50A,
Name
Set when using the optional dedicated
brake resistor.
0: Brake resistor (MRS type), brake unit
(BU type) (1.5K or more)
1: High-duty brake resistor (FR-ABR)
Set when using the optional high-duty
brake resistor (FR-ABR). Setting can be
made when b1=1. Set 10% in Pr. 561
when using the FR-ABR.
