• Surface mount Constructed with surface mount components.
technology:
• Complete isolation: Complete isolation from input to output.
• Silent operation: Carrier frequency is 20KHz.
• Short circuit protection: Complete short circuit and ground fault protection.
• LED diagnostics: red LED(S) illuminate to display various fault conditions and a green LED
illuminates to indicate normal operating conditions.
• Encoder emulation: Encoder emulation comes standard with line driver outputs,
quadrature and zero index.
• Frequency response 750 Hz minimum.
(Velocity Loop):
• Frequency response 2 KHz minimum.
(Current Loop):
• Dual signal inputs: Two single-ended or one differential. Both single-ended inputs may be use
simultaneously. All inputs have up to 15,000 A/V gain, and all inputs will
accept ±13VDC.
• Dual mode operation: The standard amplifier may be configured for simulated velocity
(RPM) control or current (torque) control.
• Current limit: Maximum motor current is adjustable.
• Digital limit/enable Three separate logic inputs can stop the motor in either or both
Inputs: directions. Inputs may be configured for active-high or
active-low, pull-up or pull-down termination, and a 0 to
+15V or 0 to +5V range.
• Encoder outputs: Incremental (quadrature) position outputs with separate index.
19 different encoder counts, from 125 to 4096
counts/revolution , are available. Differential line-
driver output devices sink and source 40mA.
• Tachometer output: DC output proportional to motor RPM.
• Fault Input/Output: Open-collector output goes low in the event of a fault. This input is
configured so that externally forcing this output low will inhibit amplifier.
This allows all fault outputs in a multi-axis system to be connected together
(wire-ORed) to shut down all amplifiers should any amplifier have a fault.
