Signalization diodes description
POWER Signalization of driver power supply
ERR /
CUR.LIM
Error signaling / current limitation:
flashing quickly - error (short circuit or overload)
blinking slowly - error (supply voltage / temperature exceeded)
on - the current limit set or driver max. current has been reached
READY
Motor operation signaling:
on - motor running (ENABLE = ON)
flashing - end limit input active (ENABLE = ON and active LIMIT N or P*)
*
active limit = high state at LIMIT input for switch LIMIT-LEVEL = OFF, or low state for switch
LIMIT-LEVEL = ON
Switches description
S1
POT-INT
Activation of speed control from the internal potentiometer
S2
POT-MODE
Current limit mode
S3
SOFT-START
Soft start function
S4
BRAKE-STOP
Braking function in the absence of ENABLE signal and limit signals
S5
LIMIT-LEVEL
Change of polarization of limit sensor inputs (S5 ON - limit switch active in
low state)
S6
AUTO-REVERSE
Automatic change of direction of rotation of the motor when reaching the
limit sensor.
2.3
Power supply
Driver power supply
To power the driver, it is recommended to use a power supply with an output voltage equal to the rated voltage of
the motor used (in the range of + 12 ... + 36 V) and current capacity appropriate to the motor power. In the case of
larger motors, the power supply should allow receiving reverse energy from the driver, which is why it is not
recommended to use stabilized power supplies, or it should be equipped with additional capacitors at the output
with a capacity of min. 4700 uF.
5V OUT
Driver faci5 V voltage which can be used for supplying of external potentiometer connected 0-5 V IN input.
Maximal current consumption for all +5 V outputs can’t exceed 100 mA.
CAUTION!
Cle5 V OUT output with ground (GND) or with power supply (VDC+) can cause damage of the driver.
2.4
Driver’s outputs
The driver has two PNP OC type outputs with max. 40 mA load. An active output causes the appearance of a VDC
supply voltage.
OUT OUT ERROR output - active in the event of a driver error
OUT LIMIT output - active when the motor reaches the set current limit. It can be used e.g. to signal
mechanical blocking of the motor, etc.
CAUTION!
The outputs are not suitable for supplying actuators (electromagnets, contactors, etc.). They are intended as
diagnostic information for a superior control system (e.g. PLC).
