3.4.1. Examples of driving by the State Machine
When using the PROFIdrive profile, the frequency reference is set to HSW. The setting
value “0x0000” - ”0x4000” is equivalent to ”0” - ”Base frequency (parameter vl)”.
When the reverse operation, the frequency reference is set with two's complement of the
forward frequency reference.
During running, HIW shows a output frequency.
3.4.1.1. Example 1. 60Hz Forward running and Deceleration stop
Set ”0x4000” to HSW and the following is set to STW in order.
0000 0100 0000 0110 (= 0x0406)
“READY TO SWITCH-ON”
0000 0100 0000 0111 (= 0x0407)
“READY TO OPERATE”
0000 0100 0100 1111 (= 0x044F)
“OPERATION”
0000 0100 0100 1110 (= 0x044E)
“OFF1 ACTIVE (Normal Stop)”
3.4.1.2. Example 2. 30Hz Reverse running
When the reverse operation, “0xE000” is set to HSW. “0xE000” is two's complement of
the “0x2000” as the forward frequency reference 30Hz.
The Setup to STW is same as the Example 1.
3.4.1.3. Example 3. Inching and pause
the following is set to STW in order.
0000 0100 0000 0110 (= 0x0406)
“READY TO SWITCH-ON”
0000 0100 0000 0111 (= 0x0407)
“READY TO OPERATE”
0000 0101 0000 1111 (= 0x050F)
“INCHING ACTIVE”
0000 0100 0100 1111 (= 0x040F)
“INCHING PAUSE”
* The inching frequency is according to the parameter f260 on VF-AS1/PS1.
