Torque
in the feed range
(base torque)
Measure the torque at minimum and maximum feed velocity. It should
not exceed 60% of the nominal torque.
Causes of excessively high base torque:
– axis lock not released
– insufficient lubrication
– excessive static friction on the slide guide rails
– incorrectly set weight compensation
– mechanical jamming of the drive axis
– unreleased holding brake
– incorrect dimensioning of the drive equipment
This should not exceed 75% of the nominal torque.
Causes of excessively high torque:
– incorrect hydraulic weight compensation
(pressure change dependent on velocity)
– fluid congestion in the toothing of an oil-flooded gear
– overtensioned toothed belt
– break in the lubrication film
– ball screw spindle not running smoothly
– incorrect dimensioning of the drive equipment
Set the weight compensation so that the motor current consumption is at
the same minimum value for upward and downward movements of the
machine axis. Carry out this check both in the feed range and in the rapid
traverse range.
Peak energy recovery:
Operate all axes simultaneously in rapid traverse mode via the NC
control and brake them using the E-STOP function. This must happen
without the power supply module cutting out with error message "bleeder
overload" or the DDS 2.1 with error message 25 "overvoltage".
Continuous energy recovery:
Run the axes of the drive package to be checked for at least 15 minutes
in the load cycle for which the highest energy recovery (braking energy)
is to be expected. The test phase must run without the supply module
cutting out with error message "bleeder overload".
If the system does cut out in either of the above cases, the power supply
setup must be corrected (see manual for power supply setup). It may be
necessary to change the power supply module or install an extension
module (TBM or TCM).
