Selecting Cooling Fan Operation
In order to increase lifetime, the cooling fan can be set to operate only when
inverter is running.
n039 = 0 (Initial setting) : Operates only when inverter is running
(Continues operation for 1 minute after
inverter is stopped.)
= 1 : Operates with power ON
Using MEMOBUS (MODBUS) Communications
Serial communication is available with VS-606V7 using programmable controller
(MEMOCON series) and MEMOBUS. Refer to MEMOBUS Instruction Manual
(Manual No.: TOEZ-C736-70.1) for details of communications.
MEMOBUS (MODBUS) communications
MEMOBUS system is composed of a single master (PLC) and slaves (1
to 31 VS-606V7 units).
Communication between master and slave (serial communication) is
controlled according to the master program with the master initiating
communication and the slave responding.
The master sends a signal to one slave at a time. Each slave has a pre-
registered address No., and the master specifies the number and conduct
signal communications. The slave receives the communications to carry
out designated functions and reply to the master.
