Emotron VSB Instruction Manual

10: Communication

Upper computer is the auxiliary frequency command source of the drive through standard
RS485 communication interface on the drive. Refer to Group H0 and appendix on this
manual for further information about communication protocol, and programming, etc.
 AT T E N T IO N :
Auxiliary frequency command can be forcibly switched to b0-04 via terminal "auxiliary
frequency command switched to digital setting b0-04". When this terminal is disabled,
master frequency command is determined by b0-03. When terminal is enabled, master
frequency command shall be the value of b0-04.
Digital setting of
b0-04
auxiliary frequency
When auxiliary frequency command is set to either 1 or 2, this parameter value should be the
initial value of auxiliary frequency command.
Range of auxiliary
b0-05
0: Relative to maximum frequency
1: Relative to master frequency
See b0-06 specification for details.
Coeff of auxiliary
b0-06
frequency command
When b0-03 selects AI, keypad potentiometer input, or process PID output as auxiliary
frequency command sources, b0-05 and b0-06 will determine the final output value of auxiliary
frequency command.
When b0-05 is set to 0 (relative to maximum frequency):
When AI or keypad potentiometer input is selected for auxiliary frequency command, the
frequency that corresponds to maximum value of the source should be (b0-08×b0-06).
