Notes:

1. The Read function of the control register is not possible. To read the ASTAT-BP status, read the Logic_Status

(Actual parameter # 1).

2. Bytes 2..8 of the control frame must be exactly as in the following example. Otherwise an error message is

returned.

3. Hardwired Stop and Soft Stop inputs override the communication. To enable motor starting through

communication, terminals 4 and 5 (Stop & Soft stop) must be connected to the control voltage.

Discrete Commands (Coils, 0x References)

The ASTAT-BP incorporates 16 "Coils", (bit parameters), of which only 5 are operative. The other 10 are reserved

and were incorporated to enable the user to use word (16 bits) type parameters. Coil # is 1"1 based". The

actual address is 1 lower than coil #. For example coil #1 is addressed as 0 (00000). The coils have the following

0x references:
