TTL Source Current = 7.9mA @ 2.4V
+10 to -10V DC analog output for forward or reverse proportional
motor speed control.
None of the terminals of the servo interface module are protected against
misapplication of AC, DC, or reverse DC.
CAUTION: Do not apply voltage or current sources to the
terminals of the servo interface module except those specified
for the terminals. Damage to the module may result.
If voltages are misapplied and damage is done to the terminal-side of the
module, the system-side including the data bus to the micro controller is
protected to 500V DC maximum isolation from the terminal side of the
module.
The line drivers and the servo amplifier of the motor drive package should
be wired to the field wiring arm connector of the servo interface module
as shown in Figure 2.1.
