9.4.4 Vertical axis
Description of function
With
a vertical axis without mechanical weight compensation, electronic weight compensation
can be set by o󹪜setting the torque limits (p1532). The torque limits speci󹪝ed in p1520 and
p1521 are shifted by this o󹪜set value. The o󹪜set value can be read in r0031 and transferred in
p1532.
To reduce compensation after a brake has been released, the torque o󹪜set can be
interconnected as a supplementary torque setpoint. As a result, the holding torque is
immediately speci󹪝ed after the brake is released.
Automatically con󹪝guring weight compensation
Siemens recommends that this function is used for vertical axes with an almost constant
force due to weight. Start the automatic determination of the force due to weight using
p1558 = 1. As soon as the technique has been started, the torque, which is required
to hold the axis, is measured and entered into p1532. Further, interconnection between
supplementary torque setpoint and p1532 is established for the precontrol, and the scaling
of the precontrol channel is set to 100%.
The measurement can be started when the pulses are inhibited or the pulses are enabled
(p1558 = 1). If the measurement was started with the pulses inhibited, it is only executed
after the pulses have been enabled. In both cases, after starting, alarm A07991 (Drive: motor
data identi󹪝cation activated) is output. The alarm is automatically withdrawn after the motor
data identi󹪝cation routine has been successfully completed.
