4-3 Operating the Converter
512C Series Converter
Note: * 8 Amp, 16 Amp and 32 Amp controllers can be scaled to currents of 4 Amp, 8 Amp or
16 Amp or less but it is recommended that lower current controllers be used in these
circumstances.
Current Motor Scaling
SW8 (OFF) Current Meter Buffered Current Meter Output
5V Equivalent to 100% of Controller Current Rating.
i.e. 4 Amp on 512C/04
8 Amp on 512C/08
16 Amp on 512C/16
32 Amp on 512C/32
SW8 (ON) Current Meter Buffered Current Meter Output
5V Equivalent to 100% of Calibrated Current Rating.
For Example 512C/16 SW5-ON,SW6-ON,SW7-OFF
Calibrated Current = 8 Amp therefore 5V = 8amp.
Potentiometers
P1 Ramp Up Rate Rotate Clockwise for Faster Acceleration to Set
Speed.
Same
(Linear :- 1 to 40 seconds) as 512
P2 Ramp Down Rate Rotate Clockwise for Faster Deceleration to Set Speed. Same
(Linear :- 1 to 40 seconds) as 512
P3 Speed Loop Stability Optimises Speed Loop Stability. ( Excessive
adjustment may lead to instability)
Same
as 512
P4 I Limit Rotate Clockwise to increase Maximum Output
Current.
With no additional connection to Torque / Current
Limit Terminal T7, the Upper Limit is 110%. To
achieve the 150% maximum connect T7 to +7.5V.
Same
as 512
P5 IR Compensation Optimises speed regulation against load change
when using Armature Voltage Feedback. Rotate
Clockwise to increase compensation and reduce
regulation.( Excess adjustment may lead to instability)
Turn Anti-clockwise when Tachogenerator Feedback
used.
Same
as 512
P6 Minimum Speed Controls Minimum Motor Speed /Setpoint when
Speed Setpoint Potentiometer connected to Terminal
4. Rotate Clockwise to increase Minimum Speed /
Setpoint. (Approximately 30% adjustment when using
10K ohm Speed Setpoint Potentiometer.)
Same
as 512
P7 Maximum Speed Controls Maximum Motor Speed. Rotate clockwise to
increase maximum speed.
Same
as 512
P8 Zero Speed Offset Adjusts Zero or Minimum Speed for Zero Speed
Setpoint.
