7.13 Equipment And Personal Safety
WinDrive contains several functions to ensure equipment and personal safety.
7.13.1 Manual Mode / Automatic Mode
Manual and Automatic operating modes are set from
the Limits Dialog box. Values are entered for both
the Manual and Automatic Mode limits for Torque
and Velocity. Manual Mode limits are always set
below those for Automatic Mode resulting in lower
Velocity or Torque operation than in Automatic
(normal) Mode.
Figure 7.54: Limits Dialog Box
7.13.2 IT Thermal Limits
The IT (current time) Limits Dialog box is opened under the
Drive/Set-up/IT Thermal Limits menu. Three limits may be set
here, the Peak Current, the Continuous Current and the IT
Time (peak current time) with IT Time being the maximum time
Peak current is allowed for. The IT Thermal Limits may be
defined as those of the motor - servo-drive configuration. To
maintain equipment safety, all three values should be set to lower
values than those corresponding to the rated peak current, the
continuous current and the peak current time of the connected
servomotor or servocontroller, whichever features the smaller
rating.
