Description
When connecting the frequency setting potentiometer at an initial
status, connect it to terminal 10.
Change the input specifications of terminal 2 when connecting it
to terminal 10E. (Refer to Pr. 73 Analog input selection in
Instruction Manual (applied).)
Inputting 0 to 5VDC (or 0 to 10V, 4 to 20mA) provides the
maximum output frequency at 5V (10V, 20mA) and makes input
and output proportional. Use Pr.73 to switch between input 0 to
5VDC (initial setting) and 0 to 20mADC when the voltage/current
input switch is in the OFF position (initially set to OFF). The
current input is always the same when the voltage/current input
switch is in the ON position (Pr.73 needs to be set to current input).
Inputting 4 to 20mADC (or 0 to 5V, 0 to 10V) provides the maximum
output frequency at 20mA (5V, 10V) makes input and output
proportional. This input signal is valid only when the AU signal is on
(terminal 2 input is invalid). Use Pr.267 to switch between input 4 to
20mA (initial setting) and 0 to 10VDC when the voltage/current input
switch is in the OFF position (initially set to ON). The current input is
always the same when the voltage/current input switch is in the ON
position (Pr.267 needs to be set to current input).
Use Pr. 858 to switch terminal functions.
(Refer to Instruction Manual (applied).)
Inputting 0 to ±5 VDC or 0 to ±10VDC adds this signal to terminal
2 or 4 frequency setting signal. Use Pr. 73 to switch between the
input 0 to ±5VDC and 0 to ±10VDC (initial setting).
Use Pr. 868 to switch terminal functions.
Common terminal for frequency setting signal (terminal 2, 1 or 4)
and analog output terminal AM. Do not earth (ground).
