Table 2- 6 This is how you select the setpoint source for the frequency
Parameters Description
P1000 = 0: No main setpoint
1: MOP setpoint
3: Fixed frequency (factory default setting)
4: USS at RS 232
6: Fieldbus
Table 2- 7 This is how you parameterize the up and down ramps
Parameters Description
P1080 = ... Minimum frequency
0.00 [Hz] factory setting
P1082 = ... Maximum frequency
50.00 [Hz] factory setting
P1120 = ... Ramp-up time
10.00 [s]
P1121 = ... Ramp-down time
10.00 [s]
Table 2- 8 This is how you optimize the starting behavior of the V/f control for a high break loose torque and overload
Parameters Description
P0003 = 2 Extended access
P1310 = ... Voltage boost to compensate resistive losses
The voltage boost is effective from standstill up to the rated speed.
The voltage boost continually decreases with increasing speed.
The maximum voltage boost is effective at speed zero and is in V:
V_ConBoost, 100 = sqrt(3) * P0305 * P0350 * (P1310/100)
P1311 = ... Voltage when accelerating
The voltage boost is effective from standstill up to the rated speed.
The voltage boost is independent of the speed.
The voltage boost in V is:
V_AccBoost,100 = sqrt(3) * P0305 * P0350 * (P1311/100)
