FCM Series
Bit 09, Local operation / bus control:
Bit 09 = "0" means that [STOP/RESET] is activated
on the control unit, or that
Local control
in parameter
002
Local/remote operation
is selected. It is not
possible to control the frequency converter via
serial communication. Bit 09 = "1" means that
it is possible to control the frequency converter
via serial communication.
Bit 10, Out of range/frequency:
Bit 10 = "0", if the output frequency has reached
the value in parameter 201
Output frequency
low limit
or parameter 202
Output frequency
high limit
. Bit 10 = "1" means that the output
frequency is within the defined limits.
Bit 11, Not running / running:
Bit 11 = "0" means that the motor is not running. Bit
11 = "1" means that the FC motor has a start signal or
that the output frequency is greater than 0 Hz.
Bit 13, Voltage OK / above limit:
Bit 13 = "0" means that the voltage limits of the
FC motor have not been exceeded. Bit 13 =
"1" means that the DC voltage of the FC motor
intermediate circuit is too low or too high.
Bit 14, Current OK / above limit:
Bit 14 = "0" means that the motor current is
lower than the torque limit selected in parameter
221. Bit 14 = "1" means that the torque limit in
parameter 221 has been exceeded.
Bit 15, Thermal warning:
Bit 15 = "0" means that the timers for motor thermal
protection and VLT thermal protection, respectively,
have not exceeded 100%. Bit 15 = "1" means that
one of the timers has exceeded 100%.
Bus reference value:
The frequency reference value is transmitted to the
frequency converter in the form of a 16-bit word. The
value is transmitted as a whole number (0-32767).
16384 (4000 Hex) corresponds to 100%. (Negative
figures are formed by means of 2
’
s complement.)
The bus reference has the following format:
Parameter 203 = "0"

Actual output frequency
The value of the actual output frequency of the
frequency converter is transmitted in the form
of a 16- bit word. The value is transmitted as
a whole number (0-32767). 16384 (4000 Hex)
corresponds to 100%. (Negative figures are formed
by means of 2

s complement).
