Setting value for the P controller of the position control loop in the IPOS
PLUS®
applica-
tion module
In the basic setting, the value of the parameter P210 P‑gain hold controller (→2201)
is accepted.
P911/912 Positioning ramp 1/2
Setting range: 0.01–1–20s
Value set for the ramp used during the positioning operation.
• The positioning ramp1 is always used in the case of a sinusoidal or square ramp
for acceleration and brake deceleration.
• In the case of a linear ramp, the brake deceleration is set depending on the ramp
mode (→2236).
– If the ramp mode "Mode1" is set, braking deceleration for travel to target posi-
tion (spot braking) only takes place with positioning ramp2. Positioning ramp1
is used for all other positioning operations.
– If the ramp mode "Mode 2" is set, positioning ramp 2 is always used during
travel for brake deceleration when changing the travel speed. Positioning
ramp1 is used for acceleration.
P913/P914 Travel speed CW/CCW
Setting range: 0–1500–6000min
-1
Speed used for positioning. It is limited by the maximum speed of the
motor(→2202).
INFORMATION
In order to prevent a lag error, always set the maximum speed about 10% greater
than the travel speed.
P915 Velocity precontrol
Parameter is only in effect with the "linear" and "jerk limited" ramp types. The function
has no effect for the ramp types "Sine" and "Squared".
Setting range: -199.99–0–100–199.99%
• Setting "100%": The drive runs optimally with regard to time using the linear velo-
city profile.
• If a value less than 100% is specified, a larger gap between position setpoint and
actual position occurs (lag distance) during a positioning operation. This results in
a "soft" run-in to the target position for the acceleration procedure.
