L: Protection Function
L parameters provide protection to the drive and motor, such as: control during momentary
power loss, stall prevention, frequency detection, fault restarts, overtorque detection, torque
limits and other types of hardware protection.

Sets the pulse output frequency in Hz when the
monitor value is 100%. Set H6-06 to "2" and
H6-07 to "0", to make the pulse train monitor
output equal to the output frequency.

L1: Motor Protection Functions

Use L1 parameters to configure motor protective functions.
Sets the motor thermal overload protection
(OL1) based on the cooling capacity of the
motor.
0: Disabled
1: Standard Fan Cooled (< 10:1 motor)
2: Standard Blower Cooled (≥ 10:1 motor)
3: Vector Motor (100:1 motor)
4: PM motor with variable torqueNOTICE:
The thermal protection is reset when the power
is cycled. In applications where the power is
frequently cycled, the drive may not be able to
provide protection, even if this parameter is set
to 1. Set to "0" and ensure each motor has a
thermal relay installed.
