P720 ·
Direct input/output functions 0 - 7
[0]
Allows direct access to the relay outputs and the analogue output via the serial
link (USS or PROFIBUS-DP with module):
0 = Normal operation
1 = Direct control of relay 1
2 = Direct control of relay 2
3 = Direct control of relay 1 and relay 2
4 = Direct control of analogue output 1 only
5 = Direct control of analogue output 1 and relay 1
6 = Direct control of analogue output 1 and relay 2
7 = Direct control of analogue output 1, relay 1 and relay 2
P721
Analogue input 1 voltage (V) 0.0 - 10.0
[-]
Read only. Displays the analogue input 1 voltage (approximate).
P722 ·
Analogue output 1 current (mA) 0.0 - 20.0
[0.0]
Allows direct control of the output current over the serial link if P720 = 4, 5, 6 or
7.
P723
State of digital inputs 0 - 3F
[-]
Read-only. Provides a HEX representation of a 6-digit binary number of which
the LSB = DIN1 and the MSB = DIN6 (1 = ON, 0 = OFF).
e.g. If P723 = B, this represents ‘001011’ - DIN1, DIN2 and DIN4
= ON, DIN3 , DIN5 and DIN6 = OFF.
P724 ·
Relay output control 0 - 3
[0]
Enables control of the output relays. Used in conjunction with P720, e.g. setting
P724 = 1 (relay 1 = ON) has no effect unless P720 = 1, 3, 5,or 7.
0 = Both relays OFF / de-energised
1 = Relay 1 ON / energised
2 = Relay 2 ON / energised
3 = Both relays ON / energised
P725
Analogue input 2 voltage (V) 0.0-10.0
[-]
Read only. Displays the analogue input 2 voltage (approximate) only when
analogue input 2 is active (P051 to P055 or P356 = 24 and the respective
digital input is high).
P726
Analogue output 2 current (mA) (MDV
only)
0.0-20.0
[0.0]
Allows direct control of the analogue output 2 current over the serial link if P720
= 4, 5, 6 or 7.
P880
Specific to PROFIBUS-DP. See PROFIBUS Handbook for further details.
Access only possible with P099 = 1
P900 to
P970
(Other than those listed below) Specific to PROFIBUS-DP and CANbus operation. See PROFIBUS or
CANbus Handbook for further details.
Access only possible with P099 = 1 or 2
P910 ·
Local / USS mode 0 - 4
[0]
Sets the inverter for local control or USS control over the serial link:
0 = Local control
1 = USS control (and setting of parameter values)
2 = Local control (but USS control of frequency)
3 = USS control (but local control of frequency)
4 = Local control (but USS read and write access to
parameters and facility to reset trips)
Note: When operating the inverter via USS control (P910 = 1
or 2 ), the analogue input remains active when P006 = 1
and is added to the setpoint.
P922
Software version 0.00 - 99.99
[-]
Contains the software version number and
cannot be changed.
P923 ·
Equipment system number 0 - 255
[0]
You can use this parameter to allocate a unique reference number to the
inverter. It has no operational effect.
P930
Most recent fault code 0 - 255
[-]
See Parameter 140
P931
Most recent warning type 0 - 99
[-]
Read only. The last recorded warning is stored in this parameter until power is
removed from the inverter. This can be cleared by using the D and Ñ buttons.
See section 7.2 for explanation of warning codes
