Description
Selects the source of motor potentiometer down signal.
Digital input DI4 (as indicated by
Digital input DI5 (as indicated by
Digital input DI6 (as indicated by
Bit pointer setting (see Terms and abbreviations
Speed reference ramp settings.
Selects the source that switches between the two sets of
acceleration/deceleration times defined by parameters
22.02...22.05.
0 = Acceleration time 1 and deceleration time 1 are in force
1 = Acceleration time 2 and deceleration time 2 are in force.
Digital input DI1 (as indicated by
Digital input DI2 (as indicated by
Digital input DI3 (as indicated by
Digital input DI4 (as indicated by
Digital input DI5 (as indicated by
Digital input DI6 (as indicated by
Bit pointer setting (see Terms and abbreviations
Defines acceleration time 1 as the time required for the speed
to change from zero to the speed value defined by parameter
19.01 Speed scaling.
If the speed reference increases faster than the set
acceleration rate, the motor speed will follow the acceleration
rate.
If the speed reference increases slower than the set
acceleration rate, the motor speed will follow the reference
signal.
If the acceleration time is set too short, the drive will
automatically prolong the acceleration in order not to exceed
the drive torque limits.
Acceleration time 1.
