CHAPTER 4 - KEYPAD (HMI) OPERATION
4.2.2
“Read-Only” Variables
and Status
Parameters P002 to P099 are reservedfor the displayof “read-only” values. The
factorydefault displaywhen power is applied to the inverteris P002. Motor speed
in rpm. The user can scroll through the various read-only parameters or use the
factory configured display of the key values. This is done by pressing the start
key
.
a)
Some selected “read-only” variables can be viewed following the
procedurebelow:
The “read-only” variable to be shown after AC power is applied to the inverter
is
defined in Parameter P205:
P205
Initial Monitoring Parameter
0
P005 (Motor Frequency)
1
P003 (Motor Current)
2
P002 (Motor Speed)
3
P007 (Output Voltage)
4
P006 (Inverter Status)
5
P009 (Motor Torque)
6
P070 (motor speed and motor current)
7
P040 (PID process variable)

- Choosing the initial monitoring parameter
NOTE!
Reference Backup
The last frequency Reference set by the keys and is stored
when the
inverter is stopped or t
he
AC power is removed, provided P120 = 1
(Reference
Backup active is the factory default). To change the frequency reference before
starting the inverter, the value of parameter P121 must be changed.
