9.5 Speed Limit
If the motor is driven by torque servo, motor speed may continuously be accelerated or
decelerated according to load status leading to excessive motor speed. It is therefore
necessary to designate maximum speed of torque servo operation to prevent the motor from
being run at a speed greater than the set level. The speed that can be limited when the
motor is run by torque servo can be set within the maximum motor speed.
The speed limit can be input freely based on the following 2 methods:
①
Using 3 digital speed commands ([Speed CMD1 (P3-01)] - [Speed CMD3 (P3-03)]
②
Using the external analog speed limit signal (absolute value input)
The selection of the internal speed command based on these 2 methods is determined as
follows according to the CN1 speed limit selection ((SPD1), (SPD2)) contacts.
