Operating instructions
4.4 Power supply
The drive power supply will be 24VDC as it is also the rated voltage of the motor.
The drive has 2 separate power supplies, one for the logic and one for the power, this is to make
it possible to cut the power of the pump from a safety circuit, even if the pump is not considered
dangerous as it has no moving part on the outside. The maximum absorption for a PCP pump is
about 2.5 A while the drive logic is about 200-300mA.
It is advisable to use cables with a minimum section of 1 mm² for connections with a length of less
than 20 m and at least 2.5 mm2 in the case of connections with a longer length (maximum length
allowed = 20 m).
Use 4- core twisted pair and shielded cables.
4.5 Ground connections
It is preferable to use a ground bar that acts as a collector especially if there are several drives
connected.
It is important to connect to ground:
• the gnd of the power supply
• the drive housing
• the expected connection provided on the power terminal board
• the power cable screen (connected via the terminal of the power terminal board)
• the encoder cable screen.
4.6 Power connector
The power connector is used to:
• bring power to the drive
• connection of the motor power supply
The connector carries the following wire diameters and tips
