Danger
High voltage and/or electrical shock. Touching live wires causes death or serious injuries!
•Consider any power cable as connected to live power, unless having proven the opposite!
•Make sure that neither end of cable is connected to live power!
•Make sure that power source cannot be engaged while work is in process!
•Obey lock-out/tag-out procedures!
•Make sure to securely lock any power engaging equipment against unintentional engagement and tag it with your name!
Requirements
•Make sure that all associated devices and components are installed according to local regulations.
•Be aware that, by principle, an electronic apparatus cannot be considered fail-safe. Therefore, you must make sure that any machine/apparatus has been fitted with
independent monitoring and safety equipment. If the machine/apparatus should break down, if it is operated incorrectly, if the control unit breaks down or if the
cables break or get disconnected, etc., the complete drive system must return—and be kept—in a safe operating mode.
•Be aware that you are not entitled to perform any repair on components supplied by Parvalux.
Electrostatic sensitive device (ESD)
• Wear working cloth and use equipment in compliance with ESD protective measures.
• Handle device with extra care.

Some contacts on the reverse side of the controller are not electrically insulated and—if the controller is not mounted as described—may cause serious injuries, respectively
may short-circuit with the mounting structure.
•When mounting to an electrically conducting surface, you must make sure that the components mounted on the controller’s reverse side cannot get in touch with the
mounting structure.
•Check the mounting structure for protruding items and eliminate them before mounting the controller.
Maximal permitted supply voltage
• Make sure that supply power is between 12…50 VDC.
•Supply voltages above 56 VDC, or wrong polarity will destroy the unit.
•Note that the necessary output current is depending on the load torque. Yet, the output current limits are as follows:
• continuous max. 15 A
• short-time (acceleration, <10 s) max. 30 A
Mounting on electrically conducting materials
Check the mounting structure for protruding items and eliminate them.
When mounting to an electrically conducting surface, you must make sure that the components mounted on the controller’s reverse side cannot get in touch with the
mounting structure.

Best practice
Keep the motor mechanically disconnected during the setup and adjustment phase.
The formula already takes the following into account:
•Maximum PWM duty cycle of 98%
•Controller’s max. voltage drop of 1 V @ 15 A
1. Use the formula below to calculate the required voltage under load.
2. Choose a power supply according to the calculated voltage. Thereby consider:
a. During braking of the load, the power supply must be capable of buffering the recovered kinetic energy (for example, in a capacitor).
b. If you are using an electronically stabilized power supply, make sure that the overcurrent protection circuit is configured inoperative within the operating
range.
Known values
•Operating torque M [mNm]
•Operating speed n [rpm]
•Nominal motor voltage UN [Volt]
•Motor no-load speed at UN; nO [rpm]
• Speed/torque gradient of the motor Δn/ΔM [rpm/mNm]

Instead of an analog voltage, a PWM signal with fixed frequency and amplitude can be used to adjust the speed set value.
The desired change in the set value is achieved by variation of the duty cycle in the range 0 … 100%. Both the amplitude and the duty cycle have an influence on the
resulting speed. The mean value of the applied PWM voltage corresponds to the analog input signal «Speed Set Value».
The specified upper limit frequency only applies to a PWM signal with a low-resistance push-pull output. If the signal is generated with an open collector or open drain
output and pull-up resistor, the upper limit frequency drops quickly.
Best practice in case of use of external potentiometer
When using an external potentiometer, the signals Vsensor and GND (connector X3, pins 5 and 7) may be used as supply. The recommended resistance of the
potentiometer is 10 kΩ.

4.1 Operation
The «SC 50/15» can operate in two modes:
•Closed loop speed control compares the actual speed signal with the applied set value. In case of deviation, the speed is dynamically readjusted.
•Open loop speed control feeds the motor with a voltage proportional to the applied speed set value. Changes in load are compensated using the IxR methodology.
The below graphs (→Figure 4-21) illustrate the relationship between the speed set value input and the controlled/ commanded motor parameters with no load connected
to the motor.
The DIP switches #1, #2, and #3 (see →Table 3-27 on page 13) define the main components of your application—the type of motor, the control mode, and the speed set
value’s source.

Figure 4-21 Operation modes – closed loop speed control vs. open loop speed control
Important: DIP switch settings during «closed loop speed control»
In control mode «closed loop speed control» (DIP switch #2 “OFF”), the configurations «PMDC motor» (DIP switch #1 “ON”) and «Hall sensor only» (DIP switches #4…#6
“OFF”) are not valid and the controller will report an error.
In «open loop speed control», the SC 50/15 operates as a voltage controller
A «Speed Set Value» of 0 (zero) VDC is equal to a motor voltage of 0 (zero) VDC and thus a speed of 0 (zero) rpm or standstill. Independent of the position of DIP switch #8
(see →Table 3-29 on page 14), the maximum speed is given by the SC 50/15’s supply voltage and the motor’s speed constant.
In case of abnormal motor behavior: Changing the Hall sensor polarity using DIP switch #7
The Hall sensor polarity cannot be determined from the outside nor can it be retrieved from the motor’s datasheet.
If, after the completed controller setup procedure, the motor is not running as expected—for example if the motor speed is fluctuating or if the motor speed is not changing
in line with the speed set value input—the Hall sensor polarity might not be according to the standard configuration. If the case, set DIP switch #7 (see →Table 3-27 on page
13) to “ON” to invert the Hall sensor polarity.
How to setup the controller
1. For closed loop speed control: Use the DIP switch #3 to select the input source of the speed set value—either analog input AnIN1 or potentiometer P1.
The set value range (0…+5.0 VDC, respectively 0%…100% PWM) is equal to a motor speed range as selected with DIP switch #8 (in correlation with DIP switches #4
through #6). The set value changes in linear fashion.
For open loop speed control:
Use the DIP switch #3 to select the input source of the speed set value—either analog input AnIN1 or potentiometer P1.
The set value range (0 … +5.0 VDC, respectively 0% … 100% PWM) is equal to a motor voltage range of 0 VDC … 0.98 x VCC. The maximum speed is determined by the
controller’s supply voltage and the motor’s speed constant and is independent on the DIP switches #4 through #8 positions. The set value changes in linear fashion.
2. If you are using the analog input AnIN1 to set the «Speed Set Value», the potentiometer P1 will adjust the speed ramp (in the range of 5 s … 20 ms) in linear fashion.
3. Adjust the potentiometer P2 to the required limiting values of Icont (in the range of 1 … 15 A) and Imax (in the range of 2 … 30 A). Both ranges are adjusted at the same time,
the limiting values change in linear fashion.
Important: The limiting value Icont should be below the motor’s nominal current (max. continuous current, refer to the →motor data sheet).
4. Slowly increase the potentiometer P3 to the required gain. The SC 50/15 will thereby use this value for thermal motor protection according to the I2t method and will
limit the output current to Icont if necessary.
Important: If the motor starts to rattle, vibrate, or making noises, the set gain is too high. If so the case, turn the potentiometer P3 in CCW direction to lower
the gain.
