A 3 phase ac line reactor should be fitted in series with the incoming main 3 phase ac power supply. (SSD Drives stock a series of reactors suitable for this duty, mechanically designed to connect directly to the controller ac supply terminals). The reactor should be connected between the controller and the ac contactor for optimum protection and safety.

Note: When the controller is operating in a regenerative mode for extended periods acting as a load generator for another machine it is advisable to fit additional protection in the armature circuit. A dc fuse or a high speed circuit breaker will provide this protection, if in doubt consult the SSD Drives Engineering Department.
To avoid damaging the drive NEVER carry out high voltage resistance or dielectric strength tests without first completely disconnecting the drive from the circuit being tested. If in doubt about the connection of the dc motor to the controller check with SSD Drives Engineering Department.

As with all power electronic drives the conducted emissions increase with motor cable length. EMC conformance to the stringent limits is only guaranteed up to a cable length of 50. This length can be increased. Refer to SSD Drives for more information.

Under certain fault conditions, larger DC protective earth currents may flow. The protective function of some RCDs cannot be guaranteed under such operating conditions. SSD Drives do not recommend the use of RCDs, but where their use is mandatory, they should be capable of correct operation with DC and AC protective earth currents (such as type B RCDs as in amendment 2 of IEC755) and have adjustable trip amplitude and time characteristics, to prevent nuisance tripping on initial power connection.

Often the coupling between electrically 'noisy' and 'sensitive' cables is a problem. This can be minimised by separating parallel runs by at least 0.25m, and minimising the length of parallel runs. For long parallel runs (>10 m) the separation should be increased proportionally. For example if the parallel runs were 50 m then the separation would be (50/10) × 0.25 m = 1.25 m.
5. TERMINAL DESCRIPTIONS 5.1 CONTROL BOARD TERMINAL DESCRIPTIONS * These Terminals should be left open-circuit if not used. AC TACH INPUT AC TACH INPUT These terminals provide input for AC tach speed measurement, rectification and filtering are provided. Selection of AC tach feedback is made via switch 1 selection. The maximum value of AC tach voltage at full speed must not exceed 200V peak.

to flow. The maximum level of this signal is later modified by the Current Limit circuit (according to the input voltages at terminals 22,23 and 25) before comparison with the Current Feedback signal SELECT AUXILIARY CURRENT INPUT* If this Terminal is connected to 0V any input at terminal 20 will be connected through to the input of the Current loop and will be added to the Current Demand Signal (see also Current Demand Isolate, Terminal 18).
Page 46
Zero Volt reference THERMISTOR/MICROTHERM Motor overtemperature sensors should be connected between Terminals 28 and 29. The drive will be disabled if the external resistance between 28 and 29 exceeds 1.8K Ohms +/-200 Ohms (see 35 and 37 Terminal descriptions). THE DRIVE MAY RESTART AUTOMATICALLY WHEN THE RESISTANCE (I.E.
Page 47
Auxiliary Enable input voltage (Terminal 30) +24V. Armature current waveform normal. ZERO SPEED RELAY DRIVE This output is intended to supply a +24 volt (D.C.) relay at an output current not exceeding 50mA. The relay should be connected between Terminals 36 and 0V; it will be energised when the Speed Feedback signal is lower than the Standstill Threshold set by preset potentiometer P4 (P4 has a range of +/-0.5 to +/-4% of Full Speed).
NOTE:- The contacts of the Contactor Control Relay are suppressed by a series connected resistor (680 ohms) and capacitor (22nF) to protect the relay contacts. Users should be aware that when the contactor Control relay is “De-energised”, a leakage current of approximately 2mA can be expected and this should be considered when interfacing to these terminals.
6. BLOCK DIAGRAM DESCRIPTION 6.1. POWER CONFIGURATION Three phase power is supplied to the AC input terminals (L1, L2 and L3) of the drive via an external isolating contactor. The phase rotation (phasing) of the supply is unimportant. Three auxiliary fuses (FS2, FS3 and FS4 ) protect the internal power wiring and suppression networks.
Page 50
5. An isolated speed feedback signal is provided by a tach or from the armature voltage using a 5590 Armature voltage isolation amplifier. It is then normalised to 10V = 100% Full Speed. 6. Isolated control power supplies are generated from the Auxiliary Supply by the switch mode supply transformer.
Page 51
The speed feedback is scaled within the drive using the calibration switches for coarse adjustment: S2 - 0/100 Volts S3 - 0/ 90 Volts S4 - 0/ 9 Volts This allows an adjustment calibration factor for full speed up to 199 Volts. P10 on the preset board will allow fine adjustment of the top speed.
For any current setting between 110% and 200% of full load, the actual current level is monitored by an overload integrating circuit. The output of this circuit pulls down the current limit setting progressively to 110% at a rate which is proportional to the overload magnitude, i.e., An inverse time characteristic which typically allows 200% current for ten seconds after which the level is automatically reduced to 110% , on a time curve which would allow 150% for about 30 seconds, and so on.
Page 53
ALARM SIGNALS The inputs to the eight input "AND" gate are: 1) PRESET BOARD: The Preset board is electrically interlocked. In the event of its removal or absence the drive is quenched and Indicator 1 is extinguished (Note: removal of the preset board whilst the drive is operating is not recommended).
Page 54
ENABLE An external Enable (Terminal 32 ) is gated with the Ready Output to produce the final inhibit signal. The drive may therefore be held in a quench condition by removing the external Enable, although the 3-phase isolating contactor is still closed. Terminal 32 must be externally connected to +24 volts before the final drive inhibit is removed and Indicator 6 is illuminated.
7.0 BASIC SETTING UP AND OPERATING INSTRUCTIONS 7.1 PRESET ADJUSTMENT DESCRIPTION Check the preset potentiometer settings on the larger plug-in card which is accessible under the front cover. The potentiometers are normally factory set to positions which will provide adequate performance in most load/controller configurations.
7.2 OPTION SWITCHES There are two user selectable option switches S8 and S9, which are located under the lower flap of the control board. Selection should only be made when the controller is isolated. S8/1 BUFFERED CURRENT SIGNAL (terminal 27) UP = ON = Armature current meter reads ±...
Page 59
S9/2 FULL WAVE FIELD SUPPLY UP = ON = Full wave rectification field supply. Typically using 415V single phase supply the field voltage will be 360V DC nominal.* DOWN = OFF = No field supply from this option. DEFAULT: ON S9/3 3 PHASE HALF WAVE FIELD SUPPLY ON = UP = 3 phase half wave field supply.
Values are selected in the factory on the basis of the best combination of standard resistor values. NOTE: The armature current calibration switches should not be changed to increase the current above the factory set value without consulting SSD Drives Limited Engineering Department. 7 - 4...
7.3.3 FIELD VOLTAGE CALIBRATION Field voltage calibration is set by selection of the option switches S9/1/2/3/4 (see S9 description). When S9/4 is selected, the field voltage can be adjusted by preset P11. By using the selection of S9/4 and P11, the most accurate setting of field voltage can be achieved.
Refer to Section 7.1 The one exception to this is the main current limit preset; note the setting of this control and then turn it fully anticlockwise. Refer to section 7.1. 6. Set option switches. Refer to section 7.2 7. Plug a Diagnostic Test Unit type 5570 into the socket on the control printed circuit board, observing correct orientation of the connector (see Diagnostic Test Facility, section 8.3).
Page 63
WARNING: DO NOT PROCEED FURTHER UNLESS THE STOP/START CIRCUITS AND CONTACTOR OPERATE CORRECTLY. 7. Turn off all power supplies to the equipment and when the whole system is totally isolated and safe, reconnect the Main 3-phase power supply. 8. Turn on Auxiliary single phase supply. 9.
The Proportional and Integral potentiometers (P5, P6, P8 and P9), as preset by SSD Drives Limited, will provide stable and responsive performance under most load conditions. Thus if instability is observed it is...
Page 65
4. To achieve Full Load Current it is necessary to override the Tach Failure Alarm/Clamp: Disconnect the Tach (+) wire from terminal 3 and then link terminal 3 to ±10V (terminal 14, 15, or 24). 5. The optimum setting of the Current Proportional and Integral presets (P8 and P9) depends, to some extent, on the setting of the Main Current Limit (P7).
Page 67
8. When the Current Loop response adjustment is completed, switch off the drive and disconnect all supplies. REMOVE THE LINK FROM BETWEEN TERMINAL 3 AND THE 10V SUPPLY AND THEN RECONNECT THE TACHO (+) WIRE TO TERMINAL 3. Return S9/5 back to its original position and reconnect the field wires to terminals D3 and D4, ensuring that they are replaced in their original positions, ie with correct polarity.
8. DIAGNOSTIC TEST FACILITY 8.1 DESCRIPTION OF DIAGNOSTIC TEST UNIT The drive is fitted with a multi-pin socket near the lower edge of the Main Control printed circuit board to allow connection of a type 5570 Diagnostic Test Unit. The Diagnostic Test Unit is small, portable, plug-in module which when connected to the drive provides access via a selector switch to 27 internal test points.
