Explanation of the parameters
Parameters
P12x Analog inputs
P120 AI2 operating
mode (optional) • NO FUNCTION: The setpoint at AI2 is not used; the external current limitation is set
to 100 %.
• 0 ... 10 V + Setpt.1: The setpoint at AI2 is added to setpoint 1 (=AI1) observing the
signs; the external current limitation is set to 100%. +/–10 V = +//–n
max
(reference
n
max
).
• 0 ... 10 V I-limit: The input serves as external current limitation. 0 ... 10 V = 0 ... 100 %
of the internally set current limitation (P303 Current limit 1 / P313 Current limit 2).
• ACTUAL VALUE CONTROLLER: Feedback of actual value for process controller (
→
P275).
• TF sensor: The TF temperature sensor integrated in the motor winding can be con-
nected to analog input AI2 for thermal protection of the drive. To activate the moni-
toring function, P530 Sensor type 1 / P531 Sensor type 2 will have to be set to the
function TF/TH sensor.
P13x / P14x Speed ramps 1 / 2
P130 ... P133 /
P140 ... P143
Ramp t11/t21
up/down CW/CCW P130 Ramp t11 up CW [s] / P140 Ramp t21 up CW [s]
P131 Ramp t11 up CW [s] / P141 Ramp t21 up CW [s]
P132 Ramp t11 up CCW [s] / P142 Ramp t21 up CCW [s]
P133 Ramp t11 up CCW [s] / P143 Ramp t21 up CCW [s]
Unit: [s]
Setting range: 0 ... 2 ... 2000 s
The ramp times refer to a setpoint step change of
∆
n = 3000 1/min. The ramp takes
effect when the speed setpoint is changed and the enable is withdrawn via the
CW/CCW terminal.
P134 / P144 Ramp
t12 / t22
UP=DOWN Unit: [s]
Setting range: 0 ... 10 ... 2000 s
The following applies to this ramp: UP = DOWN and CW = CCW.
Ramps t12 / t22 are activated by a binary input (
→
P610 ... , which is set to the function
"Ramp switchover").
