Chapter 7 - Drive Parameters
Reference input signal minimum level can be set to either
0 V / 0 mA or 2 V / 4 mA. The latter value provides a “living zero”
function. The drive will stop if the reference drops below the
minimum limit. Refer to figure 4-1 on page 24 for selection
between current and voltage input.
JOYSTK 0V0mA
JOYSTK 2V4mA
Joystick type reference has 0 Hz at 50% reference. Refer to
figure 7-3, below.
WARNING! If a 0-10 V (0-20 mA) signal is used in joystick
control, the drive will run at MAX FREQ Reverse if the control
signal is lost. For joystick control, we recommend that you use
JOYSTK 2 V/4 mA offset which will cause the drive to stop if
parameter AI-FAULT has been enabled (refer to page 67) and
the control signal is lost.
