8.1 Application Example
Setup procedure for a simple application
Motor: | 220 V | |
| 1.5 kW output power | |
Application requirements: | Setpoint adjustable via potentiometer 0 - 50 Hz | |
| Ramp up from 0 to 50 Hz in 15 seconds | |
| Ramp down from 50 to 0 Hz in 20 seconds | |
Inverter used: | MM150 | |
Settings: | P009 = 2 (all parameters can be altered) | |
| P081 | - P085 = values given on motor rating plate |
| P006 | = 1 (analogue input) |
| P002 | = 15 (ramp up time) |
| P003 | = 20 (ramp down time) |
This application is now to be modified as follows:
Operation of motor up to 75 Hz | i.e. | V |
|
|
(voltage/frequency curve is linear up to 50 Hz). |
|
| ||
| 220 |
|
| |
Motor potentiometer setpoint in addition to |
|
|
| |
analogue setpoint . |
|
|
|
|
Use of analogue setpoint at maximum 10 Hz. |
|
|
|
|
Ramp times to remain the same. |
| 50 | 75 |
|
|
| f (Hz) | ||
|
|
|
|
Parameter adjustments: | P009 = 2 | (all parameters can be altered) | ||
| P013 | = 75 | (maximum motor frequency in Hz) | |
| P006 | = 2 | (setpoint via motor potentiometer or fixed setpoint) | |
| P024 | = 1 | (analogue setpoint is added) | |
| P022 | = 10 | (maximum analogue setpoint at 10 V = 10 Hz) | |
8.2 USS Status Codes
The following list gives the meaning of status codes displayed on the front panel of the inverter when the serial link is in use and parameter P001 is set to 006:
001Message OK
002Slave address received
100Invalid start character
101Timeout
102Checksum error
103Incorrect message length
104Parity fail
Notes
(1)The display flashes whenever a byte is received, thus giving a basic indication that a serial link connection is established.
(2)If ‘100’ flashes on the display continuously, this usually indicates a bus termination fault.
