Parameter Function
Dependency: See P1175.
Note: If P1175 is set, P2150 is also used to control the Dual Ramp function.
P2151[0...2] CI: Speed setpoint for
messages
Selects the source of setpoint frequency, actual frequency is compared with this frequency to detect fre-
quency deviation (see monitoring bit r2197.7).
P2155[0...2] Threshold frequency f_1
[Hz]
Sets a threshold for comparing actual speed or frequency to threshold values f_1. This threshold controls
status bits 4 and 5 in status word 2 (r0053).
P2156[0...2] Delay time of threshold
freq f_1 [ms]
Sets delay time prior to threshold frequency f_1 comparison (P2155).
P2157[0...2] Threshold frequency f_2
[Hz]
Threshold_2 for comparing speed or frequency to thresholds.
Dependency: See P1175.
Note: If P1175 is set, P2157 is also used to control the Dual Ramp function.
P2158[0...2] Delay time of threshold
freq f_2 [ms]
When comparing speed or frequency to threshold f_2 (P2157) this is the time delay before status bits are
cleared.
P2159[0...2] Threshold frequency f_3
[Hz]
Threshold_3 for comparing speed or frequency to thresholds.
Dependency: See P1175.
Note: If P1175 is set, P2159 is also used to control the Dual Ramp function.
P2160[0...2] Delay time of threshold
freq f_3 [ms]
When comparing speed or frequency to threshold f_3 (P2159) this is the time delay before status bits are
set.
P2162[0...2] Hysteresis freq. for over-
speed [Hz]
Hysteresis speed (frequency) for overspeed detection. For V/f control modes the hysteresis acts below the
maximum frequency.
P2164[0...2] Hysteresis frequency
deviation [Hz]
Hysteresis frequency for detecting permitted deviation (from setpoint) or frequency or speed. This fre-
quency controls bit 8 in status word 1 (r0052).
P2166[0...2] Delay time ramp up com-
pleted [ms]
Delay time for signal that indicates completion of ramp-up.
P2167[0...2] Switch-off frequency f_off
[Hz]
