Important instructions
•
Protect the PMCprimo Drive2 from impermissible stresses. In particular, do not let any
components become bent or any insulation distances altered during transport and handling.
Avoid contact with electronic components and contacts.
•
Check the combination of PMCprimo Drive2 and motor. Compare the rated voltage and current
of the units. Carry out the wiring according to the connection diagram on page 31.
•
Make sure that the maximum permissible rated voltage at the terminals L1, L2, L3 or +DC,
–DC is not exceeded by more than 10% even in the most unfavourable case (see EN 60204-1
Section 4.3.1). An excessive voltage on these terminals can lead to destruction of the regen
circuit and the PMCprimo Drive2.
Use the PMCprimo Drive2 only on an earthed 3-phased supply system, to drive a synchronous
servomotor of the PMCtendo AC1 or PMCtendo AC2 series.
•
The fusing of the AC supply input and the 24V supply is installed by the user (⇒ page 21).
•
Take care that the PMCprimo Drive2 and motor are earthed properly. Do not use painted (non-
conductive) mounting plates.
•
Route power and control cables separately. We recommend a separation of at least 20 cm.
This improves the interference immunity required by EMC regulations. If a motor power cable
is used which includes cores for brake control, the brake control cores must be separately
shielded. Earth the shielding at both ends (⇒ page 49).
•
Install all heavy-current cables with an adequate cross-section, as per EN 60204.
•
Wire the BTB/RTO contact in series into the safety circuit of the installation. Only in this way is
the monitoring of the PMCprimo Drive2 assured.
•
Install all shielding with large areas (low impedance), with metallized connector housings or
shield connection clamps where possible.
•
Ensure that there is an adequate flow of cool, filtered air into the bottom of the switchgear
cabinet. See page 21.
•
It is permissible to alter the PMCprimo Drive2 settings by using the setup software.
Any other alterations will invalidate the warranty.
Caution
Never disconnect the electrical connections to the PMCprimo Drive2 while it is live. In un-
favourable circumstances this could result in destruction of the electronics.
Residual charges in the capacitors can have dangerous levels up to 300 seconds after
switching off the mains supply voltage. Measure the bus voltage at the DC-link pins (+DC/-
DC), and wait until the voltage has fallen below 40V.
Control and power connections can still be live, even when the motor is not rotating.
