12 CONSTANT
SPEEDS
Constant speed selection and values. It is possible to define three
positive constant speeds. You can select constant speeds with digital
inputs and activate by selecting Constant Speed macro with parameter
9902.
1202
CONSTANT
SPEED 1
Defines constant speed 1 (i.e. drive output frequency).
10
0…250 Hz
Output frequency
1203
CONSTANT
SPEED 2
Defines constant speed 2 (i.e. drive output frequency).
20
0…250 Hz
Output frequency
1204
CONSTANT
SPEED 3
Defines constant speed 3 (i.e. drive output frequency).
50
0…250 Hz
Output frequency
13 ANALOG INPUTS
Analog input signal processing
1301
AI MIN
Defines the minimum %-value that corresponds to the minimum mA/(V)
signal for the analog input . When used as a reference, the value
corresponds to the zero reference.
0…20 mA 0100%
4…20 mA 20100%
0
0% or 20%
Value in percent of the full signal range.
Example: If the minimum value for analog input is 4 mA, the percent
value for 0.20 mA range is:
(4 mA / 20 mA) · 100% = 20%
14 RELAY OUTPUTS
Status information indicated through relay output.
1401
RELAY OUTPUT
Selects a drive status indicated through relay output RO. The relay
energises when the status meets the setting.
FAULT(-1)
FAULT(-1)
Inverted fault. Relay is de-energised on a fault trip.
RUN
Running: Start signal on, Run Enable signal on, no active fault.
FAULT
Fault
20 LIMITS
Drive operation limits
2007
MINIMUM
FREQUENCY
Defines the minimum limit for the drive output frequency.
0
0…250 Hz
Minimum frequency.
2008
MAXIMUM
FREQUENCY
Defines the maximum limit for the drive output frequency.
50
0…250 Hz
Maximum frequency.
The following two examples illustrate the frequency reference in relation
to the drive output maximum and minimum frequency.
