Product Overview 3-2
AC30V series Variable Speed Drive
Control Features
The drive 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.
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)
Voltage Boost for V/F
control
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 with adjustable skip band width
User selectable preset speeds
Ramp, Coast, DC Injection, Quickstop
Symmetric or asymmetric ramp up and down rates
Programmable MOP function
Full diagnostic and monitoring facilities
Output short line to line, and line to earth
Overcurrent > 220% HD current
Stall
Heatsink overtemperature
Motor Thermistor overtemperature (using optional GPIO)
Overvoltage and undervoltage
Adjustable 110% (Normal Duty) or 150% (Heavy Duty)
180% shock load limit (Heavy Duty)
Normal duty (110% overload for 60s)
