Bit 3 is an inverter fault indicator. This is mapped from STW1 bit 3.
When bit 3 is inactive (no fault), bit 0 is the inverter running indicator mapped from
STW1 bit 2.
When bit 3 is active (fault), bit 0 is an AS-i fault acknowledge received indicator
(not mapped directly from the inverter).
Bits 1 and 2 are general purpose output bits. The function of these two bits are
controlled by P2041[0] and P2041[1] respectively. For this purpose the PZD is
mapped as a linear bit address space from STW1 bit 0 to bit 15 and the word
mapped to P2051.1 bit 0 to bit 15. The number written to P2041[0] and P2041[1]
controls which of these bits is mapped to bits 1 and 2 of the AS-i message from the
inverter.
NOTE
The PZD from the inverter is linked through P2051[0] to P2051[3].
Examples
1. Bit 1 should indicate status word 1 bit 11: motor current warning. (Bit 11 in
r0052)
To achieve this, set P2041[0] to 0 * 16 + 11 = 11.
2. Bit 1 should indicate status word 2 bit 9: ramping finished. (Bit 09 in r0053)
To achieve this, set P2051[0] to 53 and P2041[0] to 0 * 16 + 9 = 9.
3. Bit 2 should indicate the state of digital input 1.
To achieve this, set P2051[1] to 722. This maps r0722 (digital input states).
Now set P2041[1] to 1 * 16 + 0 = 16.
NOTE
Bit 0 and Bit 3 are fixed.
Example 1 and 2 are mutually exclusive.
