Motor Zero-speed Level
Default: 0
Settings 0–65535 rpm
 If Pr.01-11 is set as “no PG feedback” control mode, it calculates by estimated rotating speed. If
Pr.01-11 is set as “PG feedback” control mode, it calculates by the actual feedback speed, which
means that motor needs to install encoder to feedback the actual rotating speed and use with PG
card or MI pulse input terminal.
 Use this parameter to set the level of motor at zero-speed. When the speed is lower than this
setting, the corresponding multi-function output terminal that is set to 43 is ON, as shown below:
 When motor installs encoder to feedback and uses with PG card, the accuracy of zero-speed
control increases.

Maximum Frequency of Resolution Switch
Default: 60.00
Settings 0.01–599.00 Hz (use with MI setting as 43).

Switch Delay Time of Maximum Output Frequency
Default: 0.000
Settings 0.000–65.000 sec.
 Use to improve unstable speed or unstable position due to insufficient analog resolution. Use with
the external terminal (setting to 43). After setting this parameter, you also need to adjust the analog
output resolution of the controller so as to work with the parameter function.
