The miscellaneous settings include scaling factors, initialization modes, and
others. This section covers some of the most important settings you may need
to configure.
Start frequency adjustment: B082 – When the inverter starts to run, the output
frequency does not ramp from 0Hz. Instead, it steps directly to the start fre-
quency (B082), and the ramp proceeds upward from there.
Initialization related: B084, B085, B094, B180 – These functions allow you to
restore the factory default settings. Please refer to 6-3 Restoring Factory
Default Settings on page 245.
Stop key enable function: B087 – This function allows you to decide whether
the stop key on the integrated operator is enabled or not.
Dynamic Braking related functions: B090, B095, B096, – These parameters are
for using the internal brake chopper so to get more regeneration torque of the
motor.
Cooling Fan Control: B092 – You can select the performance of the cooling fan
(if your inverter model includes a fan). This function controls whether the cool-
ing fan stops or keeps on running after the inverter stops the motor. This can
result in an additional energy saving and extends fan life.
