Chapter 7 - Drive Parameters
REF OFFSET
0 V/0 mA
2 V/4 mA
Reference input signal minimum level can be set to either
0V/0mA or 2V/4mA. The latter value provides a
“living zero” function. The drive will stop if the reference
drops below the minimum limit. Refer to Figure 4-1on page
22 for selection between current and voltage input.
JOYSTK 0V0mA
JOYSTK 2V4mA
Joystick type reference has 0 Hz at 50% reference. Refer to
Figure 7-2, 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 64) and the control signal is lost.
