MaxFreq
FrqDelta
Enables the acceleration ramp setting:
OPT. DESCR. FUNCTION
0 MaxFreq
Allows accelerating or
decelerating with the same
ramp based on the
maximum
frequency,
independently from the
operating frequency.
1 FrqDelta
Allows defining the
accelerating/decelerating
time which will reach the
next speed reference
when working at constant
speed.
NO
bA.9 Time scale 01s
0.01s
0.1s
1s
Set the time scale for all time-related values. It
is particularly useful when a more accurate
Acc/Dec times are required because of load
characteristics, or when the maximum time
range needs to be extended.
OPT. DESCR. FUNCTION
0 0.01s minimum unit: 0.01 s
1 0.1s minimum unit: 0.1 s
2 1s minimum unit: 1 s
NO
bA.10
Input
Frequency
60Hz
60Hz
50Hz
Set the input frequency. If the frequency
changes, so do all related settings (base
frequency, maximum frequency…).
OPT. DESCR. FUNCTION
0 60Hz
Set drive frequency to
60Hz.
1 50Hz
Set drive frequency to
50Hz.
NO
bA.11 Pole Number (*) 2 to 48
Set the number of poles in the motor
according to its nameplate.
NO
bA.12 Rated Slip (*) 0 to 3000rpm
When a heavy load produces a big slip during
the start, configure this parameter to
compensate the motor slip.
NO
