- Page 11 In the final application the equipment must be enclosed to prevent the operator coming into contact with any high voltages. The PK2 drives are not EMC compliant, they are sold as a complex component for use by professional assemblers of motion control systems.
- Page 12 The mains input to the drive must be Installation Category II maximum. PK2 drives can be used in a Pollution Degree 2 environment i.e., one in which only non-conductive pollution occurs. You should install the drive system in an enclosure to protect it against atmospheric contaminants such as oil, moisture, dirt and to prevent operator access.
- Page 13 Do not attempt to use a 5-lead motor with this drive. NOTE: If the PK2 was sold with a QM or RM motor (sold in the USA) refer to the "Digiplan Motor User Guide" supplied with the motor, or call Digiplan USA.

- Page 17 CHAPTER 2. INSTALLATION 11 Control Signal All control signals and motor connections are made to a two-part Connections terminal block. Signal connections should be made with a minimum wire size of 7/0.2mm (24 AWG). To reduce the effect of radiated electrical noise it is suggested to use screened cable for all control signals and care should be taken to ensure that the screen is grounded at one end only.
- Page 18 12 PK2 PACKAGED STEPPER DRIVE Energise/Reset : This input enables the motor to be de-energised and also resets a fault condition, provided the cause of the fault has been removed. When the input is taken high, the drive will be de- energised and if it is safe to do so, the motor shaft may be rotated slowly by hand.
- Page 19 CHAPTER 2. INSTALLATION 13 Switches 3-6: Current set The following table gives the settings of these four switches for various motor currents. The actual motor current will depend partly on winding inductance, a lower inductance giving a lower average current. Note that the drive current is reduced by approximately 50% at standstill.
