Toshiba VF-A7 Minimum acceleration/deceleration times, Acceleration/deceleration patterns, 

■Parameter setting

a) Operation mode: Terminal board operation

Set the operation command mode selection  at .

b) Switching terminals: S3 and S4(Other terminals also can be settled for this purpose.)

S3：Acceleration/deceleration switching #1

S4：Acceleration/deceleration switching #2

■Acceleration/deceleration patterns

Acceleration and deceleration pattern can be selected individually for each of the acceleration/ deceleration times #1, 2, 3 and 4.

1)Linear acceleration/deceleration

2)S-pattern acceleration/deceleration #1

3)S-pattern acceleration/deceleration #2

★Refer to 6.23.1 for an explanation of the acceleration/deceleration patterns.

★The settings of the S-pattern lower limit adjustment amount  and the S-pattern upper limit adjustment amount  are reflected in every acceleration/deceleration pattern.

6.23.3 Minimum acceleration/deceleration times

 ：Acceleration/deceleration lower limit

・Function

This parameter sets the minimum acceleration and deceleration times.

Note) To set the minimum acceleration or deceleration time to less than 0.1 second, set (Decimal place number of acc/dec time) at (0.01 second) in advance so that the time can be displayed in units of 0.01 second.

Refer to 6.29.4 for the parameter (Decimal place number of acc/dec time).
