11.15.4.2 (ID 1060) Feedforward Gain
Location in the menu: P3.13.4.2
Use this parameter to adjust the gain of the feedforward signal.
11.15.4.3 (ID 1061) Feedforward 1 Source Selection
Location in the menu: P3.13.4.3
Use this parameter to select the source of the PID feedforward signal.
11.15.4.4 (ID 1062) Feedforward 1 Minimum
Location in the menu: P3.13.4.4
Use this parameter to set the minimum value of the feedforward signal.
11.15.4.5 (ID 1063) Feedforward 1 Maximum
Location in the menu: P3.13.4.5
Use this parameter to set the maximum value of the feedforward signal.
11.15.5 Sleep Function
11.15.5.1 (ID 1016) SP1 Sleep Frequency
Location in the menu: P3.13.5.1
Use this parameter to set the limit below which the output frequency of the drive must stay for a set time before the drive goes to
the sleep state.
The value of this parameter is used when the signal of the PID controller setpoint is taken from the setpoint source 1.
Criteria for going to sleep mode:
• Output frequency remains below sleep frequency for longer than defined sleep delay time.
• PID feedback signal remains above defined wake-up level.
Criteria for waking from sleep
• PID feedback signal falls below defined wake-up level.
