4 Parameter Settings and Functions
4.2.6 Contact Input Speed Control
4-36
Smooth speed control can be performed by inputting a progressive speed reference or
using contact input speed control. Set each constant to 0 for normal speed control.
Set these parameters as follows:
• Pn305: The time interval from the time the motor starts until the motor maximum
speed is reached.
• Pn306: The time interval from the time the motor is operating at the motor maximum
speed until it stops.
„ Operation by Contact Input Speed Control
The following describes operation by contact input speed control.
Start and Stop
The following input signals are used to start and stop the servomotor.
• Use the following table when contact input speed control is used.
Note: 1. 0: OFF (high level); 1: ON (low level)
2. Input signals indicated by the horizontal bar (-) are optional.
• When contact input speed control is not used, input signals are used as external torque
limit inputs.
