34 AGL50-EV
Linear deceleration (m/s

) with ramp set 2.
S.245 Jerk dec end 2 (linked to F.258) 1.00 0.01 10.00
Jerk (m/s
3
) applied at the beginning of a deceleration with ramp set 2.
S.250 Cont close delay (linked to A.080) 0.20 0.00 10.00
Delay time (s) for safe closing or the run contactor.
S.251 Magnet time (linked to A.081) 1.00 0.00 10.00
Duration (s) of the initial magnetization of the motor with DC injection.
S.252 Brake open delay (linked to A.082) 0.20 0.00 10.00
Delay time (s) between the open command and effective opening of the mechanical brake.
S.253 Smooth start dly (linked to A.083) 0.00 0.00 10.00
Duration (s) of the smooth start phase.
S.254 DCBrake stp time (linked to A.084) 1.00 0.00 10.00
Duration (s) of the stopping phase, after the speed has fallen below the zero threshold (dened by parameter P.440). During
this phase, the inverter can either output a DC current, or maintain a low frequency, in order to compensate for the slip
(default), as programmed by S.260.
S.255 Brake close dly (linked to A.085) 0.20 0.00 10.00
Delay time (s) between the close command and the effective engagement of the mechanical brake.
S.256 Cont open delay (linked to A.086) 0.20 0.00 10.00
Delay time (s) between the open command and the affective opening of the run contactor.
S.260 Lift stop mode (linked to A.220) [1] Normal stop
After the car speed falls below the zero threshold (dened by P.440), the inverter can be programmed to brake with DC
injection (S.260 = 0), or to maintain a low frequency output in order to compensate for the estimated slip (S.260 = 1). The
latter is set by default.
Possible selections: [0] DC brake at stop
[1] Normal stop
S.300 Manual boost [%] (linked to P.120) 3.0 0.0 25.0
Voltage boost (% of motor rated voltage) applied at low frequency in order to maintain the machine ux.
S.301 Auto boost en (linked to P.122) [0] Disable
The automatic boost allows for precise compensation of the resistive voltage drop due to the winding resistance, keeping the
ux at its rated value regardless of the load level and output frequency. For correct operation of this function, a precise value
of the equivalent stator resistance is needed.
Possible selections: [0] Disable
[1] Enable
S.310 Slip compensat (linked to P.100) 50 0 250
Amount of slip compensation (% of rated slip, calculated from nameplates) during motoring (power ows from motor to load).
S.311 Slip comp regen (linked to P.102) 50 0 250
Amount of slip compensation (% of rated slip, calculated from nameplates) during regeneration (power ows back from load
to motor).
S.312 Slip comp lter (linked to P.101) 0.3 0.0 10.0
Time constant (s) of the lter used for slip compensation. The lower this value, the faster the compensation, with improved
speed control. Excessively fast slip compensation may cause unwanted oscillations.
S.320 DC braking level (linked to P.300) 75 0 100
Amount of current (% of drive rated current) injected during magnetization and stopping phases.
S.400 Control mode (linked to P.010) [0] V/f OpenLoop
Set this parameter to “[0] Open loop V/f” when there is no encoder feedback available.
Set to “[1] Closed loop V/f” otherwise.
Possible selections: [0] V/f OpenLoop
[1] V/f ClsdLoop
