Description Menu
Controller **
Æ Parameter setting of the speed controller
(KP, TN, TV, TA, KL)
Æ Entry of the max. torque
Æ
Entry of the max. speed
In the ”Controller” menu, the speed and position controller ( 39) is to be
parameterised (exception: torque control). Apart from the controller
parameters KP (P component), TN (integral action component), TV (differential
component) and TA (scanning time), the maximum torque and the maximum
speed are to be defined in this application.
If a following error or position control should be realised, the position control
gain (KL), the following error window, or the positioning window are to be
parameterised.
Travel data sets
Æ Controller type: speed controller
Æ
Setpoint: positive
Æ Setting of setpoint speed by means of slide
control
Æ
Setting of torque by means of slide control
Æ Setting of the acceleration and deceleration
ramp
First the controller type (speed controller) is to be defined in the ”Travel data
sets” menu. Afterwards the speed setpoint is to be set via the ”Speed” slide
control, the max. torque of this travel data set via the ”Torque” slide control,
and the sign of the setpoint is to be set via the selection ”Setpoint
(positive/negative)”. For first commissioning it is advisable to select a small
speed setpoint (e. g. 300 rpm) and for safety reasons to select a torque that is
settled below the rated torque.
Furthermore, the acceleration and deceleration ramps are to be defined. If this
information has been given, all required parameters for initial commissioning
are set.
Starting the drive
Æ Press ”Start #0” in the menu bar
For starting the control, either press ”Start #0” in the menu bar, or activate the
”Start button” in the ”Travel data sets” menu. The drive is stopped again by
pressing the ”Stop button”. Pressing the ”Stop button” twice results in an
immediate standstill of the drive, disregarding the deceleration ramp.
* The settings on the ”Service” tab (current factor, max. motor torque, max. motor speed, brake available, as well as
engagement and disengagement time) for 931M drives are already preset by the factory and do not need to be
adjusted. These adjustments therefore are only required for 931W drives.
** The controller parameters KN, TN, TV, TA and TL are predefined by the factory so that for most applications a stable
system behaviour can be achieved by these settings. For an operating test, they can generally be accepted without
an adjustment.
