6.24 Operating a synchronous motor
, : PM motor constant 1
, : Step-out detection current level/ detection time
This parameter is used only when the inverter is used with a synchronous motor. If you intend to use your inverter with
a synchronous motor, contact us at the your supplier.
6.25 Acceleration/deceleration 2
6.25.1 Setting acceleration/deceleration patterns and switching
acceleration/deceleration patterns 1 and 2
: Acceleration time 2
: Deceleration time 2
: Acceleration/deceleration 1 pattern
: Acceleration/deceleration 2 pattern
: Panel acceleration/deceleration selection
: Acceleration/deceleration switching frequency
• Function
Four acceleration times and two deceleration times can be specified individually. The selection/switching
mode can be selected from the following 3 options:
1) Selection by means of parameters
2) Switching by means of frequencies
3) Switching by means of terminals
[Parameter setting]
Title Function Adjustment range Default setting
Acceleration time 2 [Note]~ sec. According to model

Panel acceleration/deceleration selection
:Acceleration/deceleration 1
: Acceleration/deceleration 2
Note:The minimum setting of acceleration and deceleration times have been set respectively at 0.1 sec. by default,
but they can be changed within a range of 0.01 sec. (setting range:0.01~600.0 sec.) by changing the setting of
the parameter (default setting).
⇒ For details, refer to Section 5.20.
