6.1.15 Starts per hour
By electronic control: unlimited
By interrupting the AC supply: <20 (equally spaced)
6.1.16 Start up time
This is the time taken from the moment of applying power and the
24 Vdc supply to the drive, to the drive being ready to run the motor:
All frame sizes -
1.5 s (this may be extended by onboard/option
module user program).
6.1.17 Output frequency / speed range
In all operating modes (Open loop, RFC-A, RFC-S) the maximum output
frequency is limited to 550 Hz.
6.1.18 Accuracy and resolution
Speed:
The absolute frequency and speed accuracy depends on the accuracy
of the crystal used with the drive microprocessor. The accuracy of the
crystal is 100 ppm, and so the absolute frequency/speed accuracy is
100 ppm (0.01 %) of the reference, when a preset speed is used. If an
analog input is used the absolute accuracy is further limited by the
absolute accuracy of the analog input.
The following data applies to the drive only; it does not include the
performance of the source of the control signals.
Open loop resolution:
Preset frequency reference: 0.1 Hz
Precision frequency reference: 0.001 Hz
Closed loop resolution
Preset speed reference: 0.1 rpm
Precision speed reference: 0.001 rpm
Analog input : 11 bit plus sign
Current:
The resolution of the current feedback is 10 bit plus sign.
Accuracy: typical 2 %
worst case 5 %
6.1.19 Acoustic noise
The cooling fan generates the majority of the sound pressure level at 1
m produced by the drive. The cooling fan on all drive sizes is a variable
speed fan. The drive controls the speed at which the fan runs based on
the temperature of the heatsink and the drive's thermal model system.
Table 6-15 gives the sound pressure level at 1 m produced by the drive
for the cooling fan running at the maximum and middle speeds.
To reduce noise emission the drive cooling fan can be set to run at
middle speed (Pr
06.045
= -7 or 7) where this is the case, an output
current derating may need to be applied. Derating information is
provided in Table 6-5 and Table 6-8.

6.1.22 Input current, fuse and cable size ratings
The input current is affected by the supply voltage and impedance.
Typical input current
The values of typical input current are given to aid calculations for power
flow and power loss.
The values of typical input current are stated for a balanced supply.
