Table 3-1 Control Features
Limited to Switching Frequency divided by 8, with a maximum of 590Hz.
e.g. for 4kHz switching frequency it is 4000/8 = 500Hz,
for 16kHz switching frequency it is 590Hz. Refer to Parker SSD for higher output frequency.
Derating of output current may apply, refer to Appendix F Technical Specifications.
Minimum 2kHz.
Maximum 8kHz – 16kHz dependent on frame size and motor type (Induction or PMAC)
0-25%
Induction motor: VHz control, Sensorless Vector Control, or Closed Loop Vector Control (with
encoder). Sensorless and Closed Loop Vector require autotune for IM.
Induction motor : Closed Loop Vector Control (with Resolver)
PMAC motor: Sensorless Vector Control
PMAC motor: Sensorless Vector Control or Closed Loop Vector Control (with resolver and
encoder (with power on constraints)
