590SP Digital Product Manual
Speed Range 100 to 1 typical when using tachometer generator feedback.
Steady State Error 2% Armature voltage feedback
0.1% Analog tachometer generator feedback
0.01% Wire-ended electrical encoder approved feedback
0.01% 5701/5901 Microtach fiber optic encoder feedback
0.0% (absolute) Quadraloc Mark II digital controller.
Encoder Resolution Maximum Microtach frequency 50 kHz
Maximum encoder frequency 100 kHz
Frequency (Hz) = Encoder Lines per Revolution × RPM ÷ 60.
Adjustments All adjustments performed with software, either by on-board push buttons and liquid crystal
display (Man Machine Interface) or through independent Windows™ software package ConfigEd
Lite. RS422 serial communications is also available as an option.
Calibration Drive normalized to motor ratings through voltage and current switch settings. Analog speed
feedback scaled through switch setable calibration board with direct-read slide switches.
(Refer to Chapter 3 for switch settings.) Fine tuning performed within drive software.
Protection All models require external branch circuit protection
