7. SUPPLEMENTARY INFORMATION
7.1 Application Example
Setup procedure for a simple application
Application requirements: Normal operating frequency set within range 15 - 50 Hz via potentiometer.
Counter-clockwise rotation required.
CombiDrive ® used: Any model.
Procedure: (1) Remove the link (if fitted) between control terminals 5 and 8.
(2) Connect a simple on/off switch to control terminals 6 and 8 for reverse
rotation.
(3) Connect a 4.7 k
Ω
potentiometer to the control terminals (see Figure 4).
(4) Set jumper JP301 (‘V’ - voltage) - see Figure 3.
(5) Set the internal and external potentiometers fully counter-clockwise and
then apply mains power and switch on.
(6) Turn the internal potentiometer clockwise until the motor rotates at a
speed that approximates to 15 Hz.
(7) The external potentiometer now has a range of between 15 Hz at its
lowest setting and 50 Hz at its highest setting.
7.2 USS Status Codes
The following list gives the meaning of status codes displayed on the OPm2 when the serial link is in use and
parameter P001 is set to 006:
001 Message OK
002 Slave address received
100 Invalid start character
101 Timeout
102 Checksum error
103 Incorrect message length
104 Parity fail
Notes
(1) The display flashes whenever a byte is received, thus giving a basic indication that a serial link
connection is established.
(2) If ‘100’ flashes on the display continuously, this usually indicates a bus termination fault.
