5-3 Programmable sequence input function (PSI)
The VAT2000 can basically be operated in three modes, from drive’s terminal block, from the operation
panel and from the serial communication ports. Input signals like RESET or EMS operate in all cases, but
some others can be enabled or disabled for operation by the changeover switches (J1, J2) or
programmable sequence input function COP. (Check fig 5-2)
The digital standard input functions in the basic PCB terminal block of VAT2000, includes three fixed
function inputs which are forward run, reset and emergency stop. There are also five programmable
digital inputs, which can be randomly assigned with functions selected from Table 5-3.
Four additional programmable inputs are available using the relay interface option card U2KV23RY0.
The standard programmable input terminals are PSI1 to PSI5. When extended, the terminals are PSI1 to
PSI9. The default settings are as shown below.
Default settings
Symbol Setting
PSI1 Reverse run
PSI2 Forward jogging
PSI3 Reverse jogging
PSI4 None
PSI5 None
The fixed input signal functions are given in Table 5-1, and the programmable input signal functions are
given in Table 5-3.
The general block diagram for vector control operation is shown in Fig.5-1..
