VACON® 3000
Application Guide
7.215 (ID 1016) SP1 Sleep Frequency
Location in the menu:
•
INU application: P3.12.4.1
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.
An incorrectly set wake-up level might not allow the drive to go into sleep mode.
7.216 (ID 1017) SP1 Sleep Delay
Location in the menu:
•
INU application: P3.12.4.2
Use this parameter to set the minimum duration that the output frequency of the drive must stay below the set limit 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.
7.217 (ID 1018) SP1 Wake-Up Level
Location in the menu:
•
INU application: P3.12.4.3
Use this parameter to set the level at which the drive wakes up from the sleep state. When the PID feedback value goes below the
level that is set with this parameter, drive wakes up from the sleep state. The operation of this parameter is selected with wake-up
mode parameter.
7.218 (ID 1033) Process Unit Minimum
Location in the menu:
•
INU application: P3.12.1.5
Use this parameter to set the minimum value of the PID feedback signal. For example, an analog signal of 4...20 mA corresponds to
the pressure of 0...10 bar. The value in process units at a 0% feedback or setpoint. This scaling is done for monitoring purposes only.
The PID controller still uses the percentage internally for feedbacks and setpoints.
7.219 (ID 1034) Process Unit Maximum
Location in the menu:
•
INU application: P3.12.1.6
Use this parameter to set the maximum value of the PID feedback signal. For example, an analog signal of 4...20 mA corresponds to
the pressure of 0...10 bar. The value in process units at a 0% feedback or setpoint. This scaling is done for monitoring purposes only.
The PID controller still uses the percentage internally for feedbacks and setpoints.
7.220 (ID 1035) Process Unit Decimals
Location in the menu:
•
INU application: P3.12.1.7
Use this parameter to set the number of decimals for the process unit values. For example, an analog signal of 4...20 mA corre-
sponds to the pressure of 0...10 bar. The value in process units at a 0% feedback or setpoint. This scaling is done for monitoring
purposes only. The PID controller still uses the percentage internally for feedbacks and setpoints.
