Section 7.2.6 Flywheel Speed

The R/D MODULE provides an isolated analog input in order for the press control to measure and display

flywheel speed (spm). If configured for motor speed adjustment, it can also provide an analog output for

setting the spm command signal to the motor drive. This interface replaces the manually adjusted speed

pot and allows the stroking speed to be directly entered into the operator terminal and automatically sent

as an analog command (0 to 10 vdc) to the drive. The module also provides an analog input for motor

current (% load). In order to interface to eddy current drives with ac tach feedback (Figure 7.12 and 7.13)

or dc drives with 0-10 vdc feedback (Figure 7.14), the 5000-6B module provides four switches (accessed

by removing the module from the card rack). These switches allow the following settings:

Switch Function Default

S4 Closed if tach is referenced to gnd on eddy current drive Closed

Open if tach wires drive a bridge rectifier on drive

S3 Closed for eddy current drives (AC tach input) Closed

Open for 0-10vdc input

S2 not used Closed

S1 Closed for 330 ohm load for current input Open

Open for 15k ohm load for current input
