Digital output (programmed as analogue input supervision) switches to "high", if AI is
higher than this value.
P7.6 Analog input supervision OFF level
Digital output (programmed as analogue input supervision) switches to "low", if AI is
lower than this value.
P7.7 and P7.8 External Brake Open Frequency and Current Limit
Thresholds that must be reached for external brake open at start.
If a digital output has been programmed for brake control, the frequency reference is
internally limited to P7.7 + 0.1Hz until the brake is opened.
P7.9 External Brake Close Frequency Limit
The brake is closed when the start command is low and output frequency is below this
threshold.
The brake is also closed whenever the drive is no more in RUN state.
P7.10 Process Source Select
Monitor V1.24 can show a process value, proportional to a variable measured by the
drive.
Source variables are:
0: PID actual value (max: 100 %)
1: Output frequency (max: f
max
)
2: Motor speed (max: speed at f
max
)
3: Motor torque (max: T
nom
)
4: Motor power (max: P
nom
)
5: Motor current (max: I
nom
)
P7.11 Process Value Decimal Digits
Number of decimals shown on monitor V1.24 and on parameter P7.12.
P7.12 Process Max. Value
Value shown on V1.24 when source variable is at its maximum.
Proportionality is kept if the source overtakes the maximum.
