Figure 15-13: Ramp Speed Scaling between
Prohibit Frequencies
513 Acceleration/deceleration ramp
speed scaling ratio between
prohibit frequency limits
Defines the acceleration/deceleration time when the output frequency is between the
selected prohibit frequency range limits (ID501 and ID502). The ramping speed
(selected acceleration/deceleration time 1 or 2) is multiplied with this factor. E.g. value
0.1 makes the acceleration time 10 times shorter than outside the prohibit frequency
range limits.
601 Motor control mode
0 Frequency control: The I/O terminal and keypad references are frequency
references and the drive controls the output frequency (output frequency
resolution = 0.01 Hz)
1 Speed control: The I/O terminal and keypad references are speed
references and the drive controls the motor speed compensating for
motor slip (accuracy ± 0.5%).
