1. "With parameter change" means that the value is actually adopted as the P0350 parameter setting and applied to the
control as well as being shown in the read-only parameters below
2. "Without parameter change" means that the value is only displayed, i.e. shown for checking purposes in the read-
only parameter r1912 (identified stator resistance). The value is not applied to the control
r1912[3] Identified stator resistance
Displays measured stator resistance value (line to line) in [Ohm].
Unit: Ohm Min: -
Index: r1912[0]: U phase
Note: This value is measured using P1910=1 or 2 , i.e., identification of all parameters with / without change.
P2000 Reference frequency
Full-scale frequency setting used by serial link (corresponds to 4000H), analog I/O and P/D
controller.
Unit: Hz Min: 1.00
P2001 Reference voltage
Full-scale output voltage (i.e. 100% ) used over serial link (corresponds to 4000H).
Unit: V Min: 10
Example P2001=230 specifies that 4000H received via USS denotes 230 V
P2002 Reference current
Full-scale output current used over serial link (corresponds to 4000H).
Unit: A Min: 0.10
r2004 Reference power
Full-scale reference power used over the serial link (corresponds to 4000H).
Unit: - Min: -
P2009[2] USS normalization
Min: 0
Settings: 0=Disabled
Index: P2009[0]: Serial interface COM link
Note: If enabled, the main setpoint (word 2 in PZD) is not interpreted as 100%=4000H, but as "absolute" instead
(e.g. 4000H=16384 means 163.84 Hz).
PZD: Process data
P2010[2] USS Baud rate
Sets Baud rate for USS communication.
Unit: - Min: 4
Settings: 4=2400 Baud
5=4800 Baud
6=9600 Baud
Index: P2010[0]: Serial interface COM link
P2011[2] USS address
Sets a unique address for the VSD.
Unit: - Min: 0
Index: P2011[0]: Serial interface COM link
Note: You can connect up to another 30 VSDs via RS-485 (i.e. 31 VSDs in total) and control them with the USS serial bus protocol.
P2014[2] USS telegram off time
Defines a time T_off after which a fault will be generated (F0070) if no telegram is received via
the USS channels.
Unit: ms Min: 0
Index: P2014[0]: Serial interface COM link
Note: By default (time set to 0), no fault is generated (i.e. watchdog disabled).
P2040 CB telegram off time
Defines time after which a fault will be generated (F0070) if no telegram is received via the link (SOL).
Unit: ms Min: 0
Dependency: Setting 0=watchdog disabled
P2041[5] CB parameter
Configures a communication board (CB)
Unit: - Min: 0
Index: P2041[0]: CB parameter 0
P2041[1]: CB parameter 1
Note: See relevant communication board Manual for protocol definition and appropriate settings.
r2050[8] CO: PZD from CB
Displays PZD (process data) received from the communication board (CB).
Unit: - Min: -
Index: r2050[0]: Received word 0
r2050[1]: Received word 1
r2050[2]: Received word 2
Note: The control words can be viewed as bit parameters r2032 and r2033.
P2051[8] CI: PZD to CB
Connects PZD to CB. This parameter allows the user to define the source of status words and
actual values for the reply PZD. (PZD: Process data).
