1 . To change the maximum output frequency corresponding to the input of the max-
imum frequency command vottage (current), value
should be
changed for Pr.903
(frequency setting voltage gain) or Pr.905 (frequency setting current gain). It is not
necessary to input a command voltage (current).
The acceleration/deceleration time is not influenced by a change in Pr.73 setting
since it defines the gradient up to the acceleration/deceleratbn reference frequen-
cy.
2. Set "0" for Pr.72 when the inverter is operated with a frequency reference poten-
tiometer connected.
*The inverter can be operated by the frequency
setting current signal (4 to 20mA DC). If the cur-
rent input signal function is set for the RWAU ter-
minal, it is possible by closing the circuit across
terminals AU and SD to use this function.
The external
run
terminal function can be set for
the starting command and rotation command.

li is possible to select the reset function for terminal
RES.
It is also possible for the parameter
unit disconnection alarm function to be selected if the parameter unit is disconnected.

if the inverter is operated without selecting the parameter unit disconnection detection function,
inverter operation will
be
continued even after the parameter
unit
is disconnected from the in-
verter, which will create hazardous situation.
*Therefore. to ensure safe operation, it is racommended that the parameter unit disconnection
detection
function be s e w e d .
*The stop key
on
the parameter unit can be activated to work in a l operation modes.
