CAUTION
• If the speed setting signal is less than the value set in Pr. 13 "starting speed", the operation is either 0
speed or servo lock.
For example, when 150r/min is set in Pr. 13, the motor will start running when the speed setting signal
reaches 150r/min.
reaches 150r/min.
• When the analog voltage command (example: across 2-5) is used as speed for operation, too low of a
setting of the rotation speed at a start may start the motor running by merely entering the start signal
although the voltage command is zero. In this case, adjustment can be made using the calibration
function, Pr. 902.

function, Pr. 902.
CAUTION
When the Pr. 13 setting is equal to or less than the Pr. 2 "minimum speed" value, note that merely
switching on the start signal will start the motor at the preset speed if the command speed is not
input.
