The soft start function is available only when contact input speed control is used with Pn000.1 set to 5, and is
not available when a pulse reference input is used. If Contact Input Speed Control Mode is switched to Pulse
Reference Input Mode while the Servomotor is operating at speed 1, speed 2, or speed 3, the Servopack will
not receive a reference pulse until the positioning completed signal /COIN is output. Always start pulse refer-
ence output from the host controller after a positioning completed signal is output from the Servopack.

The above figure illustrates signal generation timing when the soft start func-
tion is used.

The value of t1 is not affected by the use of the soft start function. A maxi-
mum 2-ms delay occurs when the /PC-L(/SPD-A) or /N-CL(/SPD-B) signal
is read.
