Please note that the ZETA replacements have all of the functionality of the OEMZL product plus Active Damping, Electronic Viscosity and Following capabilities.

Parker Stepper Drive (OEMZL Series)

The OEMZL4 microstepping drive incorporates two advanced damping technologies, Anti-Resonance and Electronic Viscosity. These unique circuits increase the performance of stepper motors by damping the resonance and ringing usually seen after quick moves. The OEMZL4 drive is perfect for multi-axis applications and allows control by any standard step and direction or clockwise/counter-clockwise controller.

Performance:

• 4 Amp @ 120VAC (170 VDC bus voltage)

• Standard step-and-direction input or CW/CCW input

• Operates with standard 1.8" hybrid step motors

• Torque from 43 oz-in (0.30 Nm) to 1907 oz-in (13.3 Nm)

Electronic Viscosity Benefits:

• Reduce settling time

• Increase slow speed smoothness (reduce velocity ripple)

• Reduce audible noise

• Anti-resonance eliminates mid-range instability and provides damping ratios of up to 0.2.

• CE marked for LVD compliance

• UL recognized

Protection Circuit:

• Motor short circuits (phase-to-phase and phase-to-ground)

• Over-temperature of internal devices and power supply

• Under-voltage (protection against low AC line or brownout)

• Power dump (dissipates excess energy caused by load regeneration)

Physical:

• 120VAC (170VDC bus voltage) operation

• Wide selection of available motors

• Removable connectors for easy installation

• Four diagnostic LEDs to confirm proper operation
