3. Controller Functions
3.1 Drive "Ready" State
The main spindle drive is "ready" when the following conditions are met:
All controller signal voltages must be present.
The control inputs and signal ouputs (terminal strip X2) must be
supplied with ±24 V and 0 V. The supply voltage should be provided
via the external controller, but the internal +24V can also be used.
The motor and controller temperatures are within permissible range:
motor winding 0 < J < 155° C
controller heatsink 0 < J < J
maxperm
The mode switch must be to the right.
There must be no fault message in the display.
The DC bus voltage must be present.
For an RAC the „E-Stop“ control input must be at 1.
For KDA3/TDA 1 the "AS" (starting lockout) control input must be at 1.
The "ready" state of the drive can be evaluated via the "READY" signal
output and the "Bb" potential-free contact.
Figure 17: Control inputs and signal output, „Bb“ potential-free contact
If the drive is "ready", it can start operating with the available functions.
The green "READY" LED comes on. If there is a fault in the drive, the
green "READY" LED is off, the red "FAULT" LED comes on and the fault
message flashes in the display.
