Voltage boost during acceleration (p1311)
The voltage boost is only effective for one acceleration operation and only until the setpoint
is reached.
Voltage boost is only effective if the signal "ramp-up active" (r1199.0 = 1) is present.
You can use parameter r0056.6 to observe whether the voltage boost is active during
acceleration.
Figure 7-8 Voltage boost during acceleration (example: p1300 = 0, p1310 = 0, p1311 > 0)
Voltage boost at startup (p1312)
The voltage boost is only effective for the first acceleration operation after pulse enable and
only until the setpoint is reached.
Voltage boost is only effective if the signal "ramp-up active" (r1199.0 = 1) is present.
You can use parameter r0056.5 to observe whether the voltage boost is active at startup.
