Precautions for Correct Use Precautions for Correct Use
• When the Overvoltage Suppression Function during Deceleration function is enabled, the
actual deceleration time is longer than the set time.
If the motor load inertia is considerably large, the motor may take a long time to stop.
To shorten the time until the motor stops, change to the deceleration stop method according to
5-12-2 Regenerative Braking Function on page 5-70.
• Setting the Overvoltage Suppression Level During Deceleration (b131) to a value less than the
input power supply voltage prevents deceleration.
Be sure to set this to a value higher than the input power supply voltage multiplied by the
square root of 2.
Normally, do not set this value to 350 V or less for 200-V class and 700 V or less for 400-V
class.
• Even when the Overvoltage Suppression Function during Deceleration function is enabled,
rapid deceleration may cause a trip error if the motor cannot respond in time.
In this case, change to the deceleration stop method according to 5-12-2 Regenerative
Braking Function on page 5-70.

Initial Screen Automatic Return Function

To enable this function, set the Initial Screen Automatic Return Function (b164) to 01 (Enabled).
When enabled, the function will automatically switch the display to the initial screen set in the Initial
Screen Selection (b038) if the Digital Operator is not operated for 10 minutes.
Parameter No.
