"Forward Acceleration" drive accelerates with direction of rota
-
tion forward .
"Forward Deceleration" drive decelerates with direction of
rotation forward.
"Reverse Acceleration" drive accelerates with direction of rota-
tion reverse.
"Reverse Deceleration" drive decelerates with direction of
rotation reverse.
"Forward Constant" drive runs with a constant speed and direc-
tion of rotation forward.
"Reverse Constant" drive runs with constant speed and direction
of rotation reverse.
Other status messages; such as error(E.xxx) and malfunction
(A.xx) codes, are described towards the end of this manual.
Operation of the Drive
Phase current
Display of the actual real-time phase current in ampere, (see also CP.5).
DC bus voltage
Display of actual DC voltage in volts.
Typical values:
CP.5 makes it possible to display the peak current within an operating cycle.
The highest value of CP.4 is stored in CP.5. The peak value in memory can
be cleared by pressing the" UP, DOWN or ENTER" key or by writing via
serial communication any value you like to the address of CP.5. Switching
off the inverter also clears the memory.
Phase current /
Peak value
Actual inverter load
Display of the actual inverter loading in percent. 100% rate of utilization is
equal to the inverter rated current. Only positive values are displayed, meaning
there is no differentiation between motor and regenerative operation.
