Pattern Operation - Toshiba TOSVERT VF-AS1 Instruction Manual

3) S-pattern acceleration/deceleration 2
Select this pattern to obtain slow acceleration in a demagnetizing region with a small motor acceleration torque. This
pattern is suitable for high-speed spindle operation.

Both the S-pattern lower-limit setting (, ) and the S-pattern upper limit setting (, )
affect all acceleration/deceleration pattern settings.

Pattern operation

 : Pattern operation selection
 : Pattern operation mode
 ,  : Number of repetitions of pattern group 1, 2
 ~  : Pattern group 1 selection 1~8
 ~  : Pattern group 2 selection 1~8
 ~  : Speed 1~15 operation time
• Function
This parameter enables you to form up to 60 patterns of automatic operation by variously combining
operation frequencies, operation times and acceleration/deceleration times.
1) Start-up by operation panel (=) : Up to 15 patterns
2) Start-up by terminal board (=) : Up to 30 patterns (15 types × 2 patterns)
Note:When control is exercised by the operation panel, pattern group 1 is always selected. If you want to operate in
a pattern other than pattern group, select pattern operation selection 1, 2, 3, or 4, using input terminal selection
parameters (~).

* Forward/reverse, acc/dec time 1, 2, V/f 1, 2 can be set with ~ (Preset speed operation frequency
1~15 operation modes). ⇒ For details, refer to Section 5.12.
Note:When the function of auto-restart is active, the time spent for speed search is added to the operation time set
for pattern operation. Consequently, the effective operation time sometimes becomes shorter than the settled
operation time.
