Pn - Parameter

The hardware current limit has a higher priority than the Pn-Parameter and could not
deactivated. The response of the hardware current limit initiates no error, that can lead
to torque dips at the motor shaft. This is of particular importance for the operation
„Hoisting and lowering“, since the drive can sack due to missing torque without
engagement of the brake.
When a function is activated the prevailing error is automatically reset.

The acceleration-/deceleration ramps can be stopped, dependent on the rate of
utilization and/or the intermediate circuit voltage. The following stopping conditions are
possible
Bit - No. Decimal
Value
Stop Conditions
0 1 Acceleration ramps are interrupted, as long as the rate
of utilization is > Pn. 5
1 2 Deceleration ramps are interrupted, as long as
the intermediate circuit voltage is > Pn. 6
2 4 Deceleration ramps are interrupted, as long as
the rate of utilization is > Pn. 5
In case several stop conditions should be activated, then the sum of the decimal
values must be adjusted.
In Pn.5 the comparison value for the LAD stop conditions (Bit 0 and Bit 2) are set. Pn.5
is compared with the actual rate of utilization. In case this is larger than Pn. 5 and the
corresponding stop conditions are activated, then the ramp is stopped. Pn. 5 is given
as the percent value, in relation to the inverter rated current.
Pn. 6 specifies the comparison value for LAD stop conditions (Bit 1). The intermediate
circuit voltage is given with a resolution of 1V. When the intermediate circuit voltage
exceeds the setpoint and the corresponding stop condition is activated, then the ramp
is stopped.
