P237 [Port0 Regis Ctrl] Configures control for Port 0 Registration:

Setting Bit 0 = 1 is the arm request to capture the position on the next trigger

event. Setting Bit 1 = 1 is the disarm request to capture on the next trigger event.

P238 [Port0 Regis Stat] Port 0 Registration Status:

Bit 0 [Armed] indicates the registration latch is armed and waiting for a trigger.

Bit 1 [Found] indicates the registration event has occurred and the value is stored

in P235 [Port0 Regis Ltch].

Power Loss/Ride Through

The precharge function provides a current limited charging of the drive's bus

capacitor(s) and, when charging is complete, bypasses the current limiting device.

This current limited charging primarily protects the drive's input fuses and front-

end rectifiers (or SCRs) from excessive inrush current. The bypass function is

needed for normal drive operation to avoid overloading the current limiting

device. In general, when precharge is active, the current limiting device is in

circuit and when precharge is done the bypass device is active (see exceptions

below).

The ride through function can provide a motor coast, precharge and auto-restart

sequence of operation in the event of an input power dropout (power loss and

return). First the drive stops PWM operation “coasting the motor” and saving any

remaining power stored in the drive's bus capacitor(s) for extended control logic

operating time. Next, the precharge function limits the drive's inrush current in

the event that the incoming power to the drive is restored. Last, after the power is
