Current- Voltage limiting functions
Limiting functions for current and voltage are available in standard E800 inverters
Current limiting function: This function allow to program a motor current threshold. If motor current reaches the
threshold (F608) during acceleration, the acceleration ramp will hold on, until current drops below the limit.
If current exceed the limit at target frequency (ramp completed), the frequency will be reduced, if necessary, down to
the minimum frequency.
Current limiting function is always deactivated during deceleration ramp.
Voltage limiting function: To limit the DC-link voltage increase, due to energy regeneration during deceleration phase.
If voltage reaches the limit (F609), the limiting function will stretch the deceleration ramp.
The limiting status of the inverter can be signalized through any programmable digital output. Function assignation
