6 Commissioning and operation
6.1 Important notes
( Stop!
The drive may only be commissioned by skilled personnel!
¯ Before commissioning remove transport locking devices and keep them for later
transports.
¯ Take safety measures prior to any operation:
– Disconnect the machine from the mains, ensure standstill of the drive system
and avoid any machine movement.
6.2 Before switching on
Check:
¯ The oil level of the gearbox after previous long−term storage!
¯ That the drive does not show any visible signs of damage.
¯ Is the mechanical fixing o.k.?
¯ Has the electrical connection been implemented correctly?
¯ Are all rotating parts and surfaces that may become hot protected against
contact?
¯ For gearboxes with ventilation:
– Has the transport locking device been removed?
( Stop!
At drive speeds below 200 rpm the amount of lubricant may need to be
increased. Consultation with Lenze is required.
6.3 Initial commissioning
In order to ensure trouble−free operation, carry out checks during initial commissioning.
When Check
At initial start−up Rotating direction of the drive shaft ()
Continuously Monitor geared motor with regard to noticeable noise, vibrations,
and changes
After 3 hours under rated load Measure housing temperature (Tab. 9) at the hottest point. The value
measured at the same time serves as a reference value for later
measurements. If necessary, implement required measures if
temperatures are rising too high, ^ 46
Fastening elements, locking screws, and covers
Leakages: small quantities of escaping lubricant
After the first day Check oil level, ^ 59
