14.2 Boost
The motor torque required during acceleration and deceleration is higher than that
required during continuous motor operation (f
). For fast acceleration and deceleration
max
settings, (steep ramps), the motor current is too high during continuous operation and
results in motor overheating. However, a lower phase current results in too flat
acceleration and deceleration ramps.
Therefore, different phase currents should be used:
Continuous operation: run current
During acceleration and deceleration: Boost current
The Boost signal is activated either by the Boost input or by ServiceBus.
