Protection Function Constants: L
The following settings are made with the protection function constants (L constants): Motor selection func-
tion, power loss ridethrough function, stall prevention function, frequency detection, torque limits, and hard-
ware protection.
Motor Overload: L1
User constants for motor overloads are shown in the following table.
H6-06
Pulse train
monitor
selection
Select the pulse train moni-
tor output items (value of the
part of U1-
).
There are two types of moni-
tor items: Speed-related
items and PID-related items.

H6-07
Pulse train
monitor
scaling
Set the number of pulses out-
put when speed is 100% in
hertz.
Set H6-06 to 2, and H6-07 to
0, to make the pulse train
monitor output synchro-
nously to the output fre-
quency.

L1-01
Motor pro-
tection
selection
Sets whether the motor over-
load function is enabled or
disabled at electric thermal
overload relay.
0: Disabled
1: General-purpose motor
protection
2: Inverter motor protection
3: Vector motor protection
In some applications when
the Inverter power supply is
turned off, the thermal value
is reset, so even if this
constant is set to 1,
protection may not be
effective.
When several motors are
connected to one Inverter,
set to 0 and ensure that each
motor is installed with a pro-
tection device.
