SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 11/2009
Description: Sets the mode for the buffer memory.
Value: 0: Save in a non-volatile fashion (RAM)
1: Buffer memory active (non-volatile)
2: Clear buffer memory
Dependency: Refer to: A01066, A01067
Caution: For p0014 = 2, entries in the buffer memory are lost and cannot be retrieved.
Notice: After the value has been modified, no further parameter modifications can be made and the status is shown in
r3996. Modifications can be made again when r3996 = 0.
Note: Re p0014 = 0:
Parameter changes are saved in the volatile memory (RAM).
Non-volatile storage from RAM to ROM is carried out in the following cases:
- p0971 = 1
- Change from p0014 = 0 to 1
Re p0014 = 1:
With this setting, alarm A01066 followed by alarm A01067 can occur if parameters are continually changed via a
fieldbus system.
Parameter changes are entered in the volatile memory (RAM) and also in the non-volatile buffer memory.
In the following cases, the entries in the buffer memory are transferred into the ROM and then the buffer memory is
cleared:
- p0971 = 1
- power down/power up the Control Unit
- Change from p0014 = 1 to 0
Re p0014 = 2:
The procedure to clear the entries in the buffer memory is initiated.
p0014 is automatically set to 0 after the entries have been cleared.
The parameter is not influenced by setting the factory setting.
Description: Displays the firmware version of the Control Unit.
Dependency: Refer to: r0197, r0198
Note: Example:
The value 1010100 should be interpreted as V01.01.01.00.
Description: Displays the currently smoothed speed setpoint at the input of the speed controller or V/f characteristic (after the
interpolator).
Dependency: Refer to: r0060
Note: Smoothing time constant = 100 ms
The signal is not suitable as a process quantity and may only be used as a display quantity.
The speed setpoint is available smoothed (r0020) and unsmoothed (r0060).
