3-10 Installing the Converter
590D DC Digital Converter - HA467078
Control Wiring Connections
Note:
Refer to Chapter 11: “Technical Specifications” for Control Terminal information.
• Use screened control cables to comply with EMC requirements.
• Control wiring must have a minimum cross-section area of 0.75mm
2
(square millimetre).
• Feed the control cables into the Converter and connect to the control terminals. Refer to the
connection label on the inside of the hinged terminal cover. Close the terminal cover.
IMPORTANT: All connections made to terminal blocks A, B and C must be isolated signal voltages.
If in doubt about the connection of the DC motor to the controller check with Parker SSD
Drives Engineering Department.
Setpoint Ramp Input (A4, A6, B3, B4)
For normal operation the speed demand signal is connected to the
"Setpoint Ramp Input", terminal A4 (Analog I/P3). This input is
scaled so that:
+10V input = maximum forward speed demand (+100%)
- 10V input = maximum reverse speed demand (-100%)
The speed demand signal can be generated by connecting the two ends
of an external 10K potentiometer to the +10V reference terminal
B3 and -10V reference terminal B4, the wiper of the potentiometer
being connected to the "Setpoint Ramp Input" as the speed
reference.
The main current limit is adjustable by means of the MAIN
CURR. LIMIT parameter [Tag No. 15]. For normal operation of
the main current limit, Terminal A6 should be connected to the
+10V reference, Terminal B3, and the CURR. LIMIT/SCALER
should be set to 200%. This allows the MAIN CURR. LIMIT
parameter to adjust the current limit between 0 and 200% full load
current. If external control of the main current limit is required, a 10K
potentiometer connected between Terminal B3 (+10V Ref) and
Terminal B1(0V), with the wiper connected to Terminal A6 (Analog
I/P5) gives 0 to 200% of full load current provided that MAIN
CURR. LIMIT and CUR. LIMIT/SCALER are set to 200%.
Signal 0V (A1)
This is the common reference point
for all analog signals used in the drive.
For non-reversing applications and 2
quadrant controller (591 and 599), the
speed demand only needs to operate
between 0V and +10V, the anti-
clockwise end of the potentiometer
should then be connected to Terminal
A1 (0V).
Speed Setpoint No. 1 (A2)
Terminal A2 (Analog Input 1) is a
direct speed demand by-passing the
"Setpoint Ramp Generator", and
should be used if direct control is
required.
Speed Setpoint No. 2 / Current Demand (A3)
Terminal A3 (Analog Input 2) is a dual function terminal (either "Speed Setpoint No. 2" or
"Current Demand") as selected by mode switch control "Current Demand Isolate", Terminal C8.
As a speed setpoint, it can be used in the same way as Terminal A2.
If more than one speed setpoint is used they are additive.
