• Selecting Cooling Fan Operation
In order to increase fan life, the cooling fan can be set to operate when inverter is
running or when power is supplied.
• Using MEMOBUS (MODBUS) Communications
Serial transmission is available with VS mini J7 using programmable controller
(MEMOCON series) and MEMOBUS. In order to perform serial communications, RS-
485/422 interface card (optional) must be installed.
• MEMOBUS (MODBUS) communications
MEMOBUS system is composed of a single master (PLC) and slaves (1 to 31
VS-mini units).
Transmission 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 conducts signal
communication. The slave receives the transmission to carry out designated
functions and reply to the master.
n35 = 0 (factory setting) : Operates only when inverter is running.
(Continues operation for 1 minute after
inverter is stopped.)
= 1 : Operates while power is ON.
