r0019.0...14 CO / BO: Operator panel
control word
- - - - - U16 3
Displays status of operator panel commands. The settings below are used as the "source" codes for
keypad control when connecting to BICO input parameters.
Bit Signal name 1 signal 0 signal
00 ON / OFF1 Yes No
01 OFF2: Electrical stop No Yes
08 JOG right Yes No
11 Reverse (setpoint inversion) Yes No
13 Motor potentiometer MOP up Yes No
14 Motor potentiometer MOP down Yes No
Note: When BICO technology is used to allocate functions to panel buttons, this parameter displays the actual
status of the relevant command.
r0020 CO: Frequency setpoint
before RFG [Hz]
- - - - - Float 3
Displays actual frequency setpoint (input of ramp function generator). This value is available filtered
(r0020) and unfiltered (r1119). The actual frequency setpoint after RFG is displayed in r1170.
r0021 CO: Actual filtered
frequency [Hz]
- - - - - Float 2
Displays actual inverter output frequency (r0024) excluding slip compensation (and resonance damping,
frequency limitation in V/f mode).
r0022 Actual filtered rotor
speed [RPM]
- - - - - Float 3
Displays calculated rotor speed based on r0021 (filtered output frequency [Hz] x 120 / number of poles).
The value is updated every 128 ms.
Note: This calculation makes no allowance for load-dependent slip.
r0024 CO: Actual filtered output
frequency [Hz]
- - - - - Float 3
Displays actual filtered output frequency (slip compensation, resonance damping and frequency limitation
are included). See also r0021. This value is available filtered (r0024) and unfiltered (r0066).
r0025 CO: Actual output
voltage [V]
- - - - - Float 2
Displays filtered [rms] voltage applied to motor. This value is available filtered (r0025) and unfiltered
(r0072).
r0026[0] CO: Actual filtered DC-
link voltage [V]
- - - - - Float 2
Displays filtered DC-link voltage. This value is available filtered (r0026) and unfiltered (r0070).
Index: [0] Compensation DC voltage channel
Note: r0026[0] = Main DC-link voltage
r0026[1] = Decoupled DC-link voltage for internal supply. It depends on the inverter topology. If it is not
available it shows the value 0.
r0027 CO: Actual output
current [A]
- - - P2002 - Float 2
Displays rms value of motor current. This value is available filtered (r0027) and unfiltered (r0068).
r0028 CO: Motor current
modulus
- - - P2002 - Float 4
Displays estimated rms value of motor current calculated from dclink current.
