DC590+ Series DC Digital Drive
Terminal Information – Control Board
This Control Board is common to all 590+ units.
Terminal Description Terminal Function Signal Level Configurable Terminal
Number
Digital Input 3
Current Demand Isolate
This input alters the drive operation from Speed
Control to Current Control. When digital input
No. 3 is true, analog input No. 2 provides the
current demand and the speed loop is
disconnected. When false the speed loop is in
control and analog input No. 2 is an auxiliary
speed setpoint.
Access encoder mode set-up & output parameters
via the ENCODER 2 function block.
+24V = True/Current
0V = False/Speed
Threshold + 16V
Encoder CLK/DIRECTION Mode: DIRECTION INPUT
+5V to +24V, or 0V
YES C8
+24V Supply
+24V Maximum output current: 200mA
Note that the maximum combined consumption for
digital outputs 1, 2 & 3 and C9 should not exceed
300mA.
