■ Parameters - Serial communication
500 Address
(BUS ADDRESS)
Value:
1 - 126
✭ 1
Function:
This parameter allows specification of the address
of each frequency converter. This feature is used
in connection with PLC/PC connection.
Description of choice:
The individual frequency converters can be given an
address between 1 and 126. The address 0 is used
if a master (PLC or PC) wishes to send a telegram
that is to be received by all frequency converters
connected to the serial communication port at the
same time. In this case, the frequency converter
will not acknowledge receipt. If the number of units
connected (frequency converters + master) exceeds
31, a repeater is required. Parameter 500 cannot be
selected via the serial communication port.
501 Baudrate
(BAUDRATE)
Value:
300 Baud (300 BAUD)
[0]
600 Baud (600 BAUD)
[1]
1200 Baud (1200 BAUD)
[2]
2400 Baud (2400 BAUD)
[3]
4800 Baud (4800 BAUD)
[4]
✭9600 Baud (9600 BAUD)
[5]
Function:
This parameter is for programming the speed
at which data is to be transmitted via the serial
connection. Baud rate is defined as the number
of bits transferred per second.
Description of choice:
The transmission speed of the frequency converter
is to be set at a value that corresponds to the
transmission speed of the PLC/PC. Parameter 501
cannot be selected via the serial port, RS 485. The data
transmission time proper, which is determined by the set
baud rate, is only part of the total communication time.
502 Coasting
(COASTING SELECT)
503 Quick-stop
(Q STOP SELECT)
504 DC-brake
(DC BRAKE SELECT)
505 Start
(START SELECT)
507 Selection of Setup
(SETUP SELECT)
508 Selection of speed
(PRES.REF. SELECT)
Value:
Digital input (DIGITAL INPUT)
[0]
Bus (SERIAL PORT)
[1]
Logic and (LOGIC AND)
[2]
✭Logic or (LOGIC OR)
[3]
Function:
Parameters 502-508 allow a choice between
controlling the frequency converter via the terminals
(digital input) and/or via the bus.
If Logic and or Bus is selected, the command
in question can only be activated if transmitted
via the serial communication port. In the case
of Logic and, the command must additionally be
activated via one of the digital inputs.
Description of choice:
Digital input [0] is selected if the control command in
question is only to be activated via a digital input.
Bus [1] is selected if the control command in
question is only to be activated via a bit in the
control word (serial communication).
Logic and [2] is selected if the control command
in question is only to be activated when a signal
is transmitted (active signal = 1) via both a
control word and a digital input.

Logic or [3] is selected if the control command in
question is to be activated when a signal is given (active
signal = 1) either via a control word or via a digital input.
