P0776 Type of DAC
Defines type of analog output
Unit: - Min: 0 Def: 1 Max: 1
Level 3
Settings:
0 Current output
1 Voltage output
Note:
The analog output is designed as a current output with a range of 0...20 mA
For the ECB variant, the 2 analog output channels must be of the same type i.e. both channels are current outputs with a
range of 0...20 mA or both channels are defined as voltage outputs with a range of DC 0...10 V
P0777[2] Value x1 of DAC scaling
Defines x1 output characteristic in [%]. Scaling block is responsible for adjustment of output
value defined in P0771 (DAC connector input)
Parameters of DAC scaling block (P0777 ... P0781) work as follows:
Unit: % Min: -99999.0 Def: 0.0 Max: 99999.0
Level 2
Data:
Defines x1 output characteristic in [%]. Scaling block is responsible for adjustment of output value defined in P0771
(DAC connector input)
Index:
P0777[0]: Analog output 1 (DAC 1) P0777[1]: Analog output 2 (DAC 2)
Dependency:
Affects P2000 to P2003 (reference frequency, voltage, current or torque), depending on which setpoint is to be generated
P0778[2] Value y1 of DAC scaling
Defines y1 of output characteristic
Unit: - Min: 0 Def: 0 Max: 20
Level 2
Index:
P0778[0]: Analog output 1 (DAC 1) P0778[1]: Analog output 2 (DAC 2)
P0779[2] Value x2 of DAC scaling Level 2
Defines x2 of output characteristic in [%]
Unit: % Min: -99999.0 Def: 100.0 Max: 99999.0
Index:
P0779[0]: Analog output 1 (DAC 1) P0779[1]: Analog output 2 (DAC 2)
Dependency:
Affects P2000 to P2003 (reference frequency, voltage, current or torque), depending on which setpoint is to be gener-
ated
P0780[2] Value y2 of DAC scaling Level 2
Defines y2 of output characteristic
Unit: - Min: 0 Def: 10 Max: 20
Index:
P0780[0]: Analog output 1 (DAC 1) P0780[1]: Analog output 2 (DAC 2)
P0781[2] Width of DAC dead band
Sets width of dead band in [mA] or [V] for analog output
Unit: - Min: 0 Def: 0 Max: 20
Level 3
Index:
P0781[0]: Analog output 1 (DAC 1) P0781[1]: Analog output 2 (DAC 2)
P0809[3] Copy command data set
Calls 'Copy command data set' function
Unit: - Min: 0 Def: 0 Max: 2
Level 3
Index:
P0809[0]: Copy from CDS P0809[1]: Copy to DDS P0809[2]: Start copy
Note:
Start value in index 2 is automatically reset to '0' after execution of function
P0810 BI: CDS bit 0 (Local / Remote)
Selects command source from which to read Bit 0 for selecting a BICO data set (see control
word 1, Bit 15)
Unit: - Min: 0:0 Def: 718:0 Max: 4095:0
Level 3
Note:
Bit 1 is also relevant for BICO data set selection
P0918 CB address
Defines address of CB (communication board) or address of the other option modules
Unit: - Min: 0 Def: 3 Max: 65535
Level 3
Data:
Defines address of CB (communication board) or address of the other option modules
There are two ways to set the bus address:
1 via DIP switches on the PROFIBUS module
2 via a user-entered value
Note:
Possible PROFIBUS settings:
1 ... 125
0, 126, 127 are not allowed
The following applies when a PROFIBUS module is used:
DIP switch =0 address defined in P0918 (CB address) is valid
DIP switch not=0 DIP switch setting has priority and P0918 indicates DIP switch setting
P0927 Parameter changeable via Level 3
Specifies the interfaces which can be used to change parameters
Unit: - Min: 0 Def: 15 Max: 15
Example:
b - - n n" (bits 0, 1, 2 and 3 set) in the default setting means that parameters can be changed via any interface
"b - - r n" (bits 0, 1 and 3 set) would specify that parameters can be changed via PROFIBUS/CB, BOP and USS on COM
link (RS-485 USS) but not via USS on BOP link (RS-232)
Bit fields:
Bit00 PROFIBUS / CB 0 NO, 1 YES
Bit01 BOP 0 NO, 1 YES
Bit02 USS on BOP link 0 NO, 1 YES
Bit03 USS on COM link 0 NO, 1 YES
r0947[8] Last fault code
Displays fault history.
Unit: - Min: - Def: - Max: -
Level 3
