Description
Control Voltage
Output voltage
Digital Input 1
FWD = clockwise rotating field enable
(U  V  W)
Digital input 2
REV = anticlockwise rotating field enable
(W  V  U)
Digital Input 3
FF1 = Switch from analog setpoint AI1 (control
signal terminal 6) to fixed frequency value f-Fix1 in
parameter P-20 (15 Hz)

Description
f-max
Hz
Maximum output frequency; can be set to any
value between f-min (P-02) and the motor's rated
frequency (P-09); maximum setting: 5 x P-09
Min Frequency
Hz
Minimum output frequency, can be set to any
value between 0 and f-max (P-01)
t-acc
s
Acceleration time from stop to rated frequency
(P-09).
