The maximum frequency inverter speed is achieved, if the MCU (within
UserTerminal) sets the control voltage (analogue voltage for frequency
inverter) at 10 volt, that is at maximum frequency inverter frequency.
The maximum speed during maximum frequency inverter frequency is
going to be set basically with the input of the correct device type at
option number 3 at the administrator level. Option 48 is necessary at
manual speed calibration or special speed transformation or drive
motors (special speeds) only.
When changing option 48, always pay attention to the correct setting of
the options number 5 (maximum speed), number 11 (speed
measurement; has to be switched on) and number 34 (speed
calibration value).
Examples for the different special speeds and the appropriate
maximum inverter frequencies are to be found in list B3: List of device
types.
Procedure
N
Make sure that the correct device type is set at administrator
option 3.
N
Go to administrator option 5 and set maximum possible speed.
N
Control at the manual mode the device with the key "+" to the
maximum possible speed.
N
Check the analogue voltage at the MCU-FU-control with a
voltmeter: it has to be 10 volt. Note down the voltage at the
service report! (not possible with digital control via RS485)
N
Read off the speed and write down the value at the h/p/cosmos
service report: OP 48: _____ km/h
N
Stop the running belt with the STOP key.
N
Go to administrator OPTION 48 and input the before measured
value in km/h (maximum possible speed at full FU-activation).
N
Go again to administrator OPTION 05 and allow the desired /
appropriate maximum speed.
Info 1: If no speed scan (speed sensor) has to be set under option 11,
the speed calibration value will be calculated automatically with option
48.
Info 2: Even if no speed scan is set, the speed calibration value has an
internal significance. In that case the scanning impulses (actual
impulse) are deduced or simulated directly from the analogue voltage
and not measured via the speed sensor input.
Range of adjustment: 1.00 to 99.99 km/h
