Product Overview
AC30 series Variable Speed Inverter
Control Features
The inverter is fully featured when controlled using the optional Keypad (or a suitable pc programming tool).
The ‘General’ control features below are not user-selectable when the unit is controlled using the analog and digital inputs and outputs.
General Output Frequency 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.
Switching Frequency Minimum 2kHz.
Maximum 8kHz – 16kHz dependent on frame size and motor type (Induction or PMAC)
Voltage Boost for V/F
control
0-25%
Motor Control Modes Induction motor: VHz control, Sensorless Vector Control, or Closed Loop Vector Control (with
encoder if fitted). Sensorless and Closed Loop Vector require autotune.
PMAC motor: Sensorless Vector Control
Skip Frequencies Skip frequencies with adjustable skip band width
Preset Speeds User selectable preset speeds
Stopping Modes Ramp, Coast, DC Injection, Quickstop
