With a gain of 1.0 and an offset of 0.0, 10V will
indicate 100% or full value based on
programmed values. For example, with the
above scenario of a gain of 1.0 and an offset of
0.0, a 10V signal an Analog Output set to arm
current would indicate 100% of rated current.
Whereas a 0V signal on the same Analog
Output would indicate 0% of rated current.
Any value over 100% will cause the analog
channel to saturate.

analog addr2
(Analog Address 2) Ability to view hex monitor functions via the
analog outputs. Choosing this function will display the hex monitor
value of ADDR2& (U8).

analog addr3
(Analog Address 3) Ability to view hex monitor functions via the
analog outputs. Choosing this function will display the hex monitor
value of ADDR3& (U8).
none
arb state
(ARB State) Ability to view which section ARB Mode is in while
setting up ARB. For further information, see Anti-Rollback on page
125.

Motor overload
0 – 10V, when the number reaches 10V the drive will shut down
and declare the fault.
0 – 100%
motor mode
(Motor Mode) Voltage level switches to indicate the mode the
current regulator is operating in.
1) Forward motoring (~ 9.7V)
2) Forward regeneration (high CEMF) (~ 4.4V)
3) Forward plugging (regeneration at low CEMF) (~ 1.3V)
