6.3 Special features when using the 82XX controller
Tip!
Reading and writing of the parameter C192x of 82XX controllers takes up to 500 ms.
6.3.1 Start with Ctrl. inhibit instead of QSP
• After mains connection with the operating mode C0001 = 3, the drive is in the status QSP.
• With C1920 = 1, the switch-on status is always Ctrl. inhibit, so that the drive can be enabled
by writing C0040 = 1.

6.3.2 Reduction of the response time of the interface
• With active reduced response time, write telegrams (send) are only checked for transmission
errors:
– If the telegram is fault-free, a positive acknowledgement (ACK) is sent, otherwise it is a
negative acknowledgement (NAK).
– Only then the value to be written is transmitted to the controller.
• The module can be readdressed under the following conditions:
– With 820X controllers after approx. 230 ms.
– With 821X/8200vector/822X controllers after approx. 50 ms.
Stop!
The acceptance of the value by the controller cannot be guaranteed.
