Unidrive User Guide 79
Issue Number: 9 www.controltechniques.com
*This parameter has a maximum range of 250Hz in Unidrive VTC.
Open-loop and Closed-loop Vector
Enter the value from the rating plate of the motor.
6.2.15 Operating-mode selection
The settings for 0.48 are as follows:
See Chapter 8 Optimisation on page 92.
The operating mode cannot be changed while the drive is running.
6.2.16 Status information
This parameter indicates the current status of the drive parameter
security system. Each digit indicates a particular aspect of security as
follows:
Units digit: 0 = Standard security has been unlocked
1 = Standard security is still set
Tens digit: 0 = User security has been unlocked or is not active
1 = User security is active preventing RW access
Hundreds digit: 1 = Pr 11.30 not equal to 149*
Thousands digit: 1 = Pr 11.30 equal to zero*
* The value of Pr 11.30 is the last value written by the user. Pr 11.30
always appears as 149 when first accessed by the key pad to hide the
real value last written by the user. If Pr 11.30 = 149 then user security is
cleared. If Pr 11.30 = 0 then user security and security preventing
access outside menu 0 is cleared.
In contrast to all the other parameters in menu 0, this parameter does
not exist in any other menu.
Displays the first two sections of the software version of the drive.
6.2.17 Unidrive VTC Menu 0 differences
Menu 0 in Unidrive VTC contains some different parameters to menu 0
in Unidrive. The following menu 0 parameters are found in Unidrive VTC.
Any parameter not listed below is the same as open loop Unidrive.
Pr 0.14 indicates the total motor current (the vector sum of Pr 0.13 Motor
active-current and Pr 4.17 Motor magnetising current).
Total output power of the drive (positive for power flow out of the drive
output terminals).
Enter the value of frequency as required. When Pr 1.10 Bipolar
reference select is set at 0, negative values are treated as zero. When
Pr 1.10 is set at 1, negative values will cause the drive to run in the
reverse direction.
