General status word (output process data)
Information about the status of the device and messages is indicated in the
General status word. The General status word is composed of 16 bits the
meanings of which are described in the table below:
Table 56. General status word (output process data)
Bit Description
Value = 0 Value = 1
B0, RDY Drive not ready Drive ready
B1, RUN Stop Run
B2, DIR Clockwise Counter-clockwise
B3, FLT No fault Fault active
B4, W No alarm Alarm active
B5, AREF Ramping Speed reference reached
B6, Z – Drive is running at zero speed
B7 – Fieldbus control active
B8 - B12 – –
Bit Control place
I/O PC tool Keypad Fieldbus
B13 1 0 0 0
B14 0 1 1 0
B15 0 1 0 1
Actual speed (output process data)
This is actual speed of the frequency converter. The scaling is
–10000...10000. The value is scaled in percentage of the frequency area
between set minimum and maximum frequency.
Control word (input process data)
The three first bits of the control word are used to control the frequency
converter. By using control word it is possible to control the operation of the
drive. The meanings of the bits of control word are explained in the table
below:
Table 57. Control word (input process data)
Bit Description
Value = 0 Value = 1
B0, RUN Stop Run
B1, DIR Clockwise Counter-clockwise
B2, RST Rising edge of this bit will reset active fault
B5,
Quick ramp time
Normal
deceleration ramp time
Quick
deceleration ramp time
Speed reference (input process data)
This is the Reference 1 to the frequency converter. Used normally as Speed
reference. The allowed scaling is 0...10000. The value is scaled in percent-
age of the frequency area between the set minimum and maximum fre-
quencies.
