P-24 Deceleration
ramp 2 0 – 25 s 0 s Via binary input or in the event of power failure
according to
P-05 .
P-25 Function selection
analog output 0 Inverter enabled (digital) 8 Binary output mode
• Options 0 – 7: Selection of a digital voltage
output signal
–
Deactivated: 0 V
– Activated: +24 V (20 mA limit value)
Analog output mode
• Option 8: Motor speed signal range
0 – 10 V = 0 – 100% of

P-26 Speed skip
function 0 – P-01 0 Hz Speed skip function: The speed runs through
hysteresis according to a velocity set in
P-03 and
P-04 .
P-27 Skip window
center P-02 (min.) – P-01 (max.) 0 Hz Middle of skip range
P-28 V/f characteristic
curve adjustment
current 0 – P-07 0 V Adjusts the present motor voltage to this value
using the frequency set in
P-29 .
P-29 V/f characteristic
curve adjustment
frequency 0 – P-09 0 Hz Sets the frequency used to apply the V/f adjust-
ment set in
P-28 .
