Programming
Bit 08 = "0" means that the actual motor speed is different
from the speed reference set. This can be the case i.e.
while the speed is ramped up/down during start/stop.
Bit 08 = "1" means that the present motor speed equals
the speed reference set.
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

DriveMotor FCM Series
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"
"ref
0-16384 (4000 Hex) ~ 0-100% ~ ref
Parameter 203 = "1"
-ref
-16384 (. . . Hex) - +16384 (4000 Hex) ~

Actual output frequency
Illustration 3.38
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).

500
Value:
Parameter 561 Protocol = FC protocol [0]
0 - 126
Parameter 561 Protocol = MODBUS RTU [3]
0 - 247
Function:
This parameter allows the allocation of an address to each
frequency converter in a serial communication network.
Description of choice:
The individual frequency converter must be allocated a
unique address. If the number of units connected
(frequency converters + master) is higher than 31, a
repeater must be used. Parameter 500 Address cannot be
selected via the serial communication, but must be preset
via the control unit.
