NOTE:
In IND, Bit 15 uses a multiplier of 2
0
, so the value of Bit 15 for the access P2000-
P3999 must be set to 1.
Parameter value (PWE) 3rd and 4th word
All parameters in VFD series Drives are 16-bit. A 16-bit parameter value is transferred
in PWE2 (4th word). PWE1 (3rd word) must be set to 0 on the PROFIBUS-DP master
in this case.
