Shortening the delivery time

When an order is placed, the availability of the components required for the end product and the production possibilities are checked. After confirmation, express production is possible within the shortened delivery time at an extra charge.

Installation position

The installation position is required to determine the lubricant quantity.
The designations for the various installation positions can be found in the following illustration.

Terminal box position

The position of the terminal box (0, 90, 180 and 270°) and the positioning of the cable entry (A, B, C and D) can be
configured as follows:

Flange size

Wave options

Double seal on the output shaft:

Depending on the available installation space, a combination seal with one NBR and one FKM sealing lip or two sealing rings in NBR and FKM design are used.

Advantages:

• Optimum sealing properties at high operating temperatures thanks to FKM seal
• Good sealing properties at low temperatures due to NBR seal
• Better protection against high levels of contamination thanks to 2 seals (the outer seal also has a dust lip)
• High safety and better stability against oil leakage due to additional sealing lip

• Critical installation positions
• where special requirements are placed on the reliability of the seal

Reinforced bearing of the output shaft

With this option, the permissible radial forces for the output shaft can be increased.
Further information on determining the radial force and the permissible values for
standard and reinforced bearings can be found in the PDF document Notes on selecting options

Reduced torsional backlash
This option reduces the torsional backlash to the maximum value specified on the respective product.
The backlash specifies the possible angle of rotation of the output shaft when the gearbox input is blocked.
Use is recommended for positioning tasks.

If required, a further reduction of the backlash may be possible on request.

Second shaft end

• Standard version - without
• Second shaft end - cylindrical shaft with keyway
• Second shaft end with handwheel - cylindrical shaft with keyway and handwheel

Dimension sheets and CAD models for the optional versions are available on request.

Dust and water protection

• IP55 - dustproof, protection against water jets (standard)
• IP65 - dust-tight, protection against water jets
• IP65 with brake - as before, but with additional brake version in IP65

IP code for the degree of protection in accordance with DIN EN 60529, 60034-5,
First code number: Protection against ingress of foreign bodies
Second code number: Protection against ingress of water with harmful effects

Voltage/frequency

• 230/400V/D/Y, 50Hz (standard)
  Possible applications: In star connection (Y) directly on 400V mains, In delta connection (D) on frequency inverters with output voltage
  output voltage 230V/3~ or on frequency converters with output voltage 400V/3~ and operation with 87Hz-
  characteristic
• 400/690V/D/Y, 50Hz
  Possible applications: In delta connection directly on the 400V mains, and on frequency inverters with output voltage
  400V/3~, star-delta start-up with switches or contactors
• 460V/Y, 60Hz
• 230/400V/D/Y, 50Hz // 460V/Y, 60Hz
• 290/500V/D/Y , 50Hz (up to 4kW possible)
• 500V/D, 50Hz (from 5.5 to 45kW possible)

Motor protection

• 1 set of PTC thermistors - for monitoring with PTC thermistor tripping device or frequency inverter
• 1 set of temperature switches (bimetal) - for monitoring e.g. with motor protection relay

The selection of one of these options is recommended when operating the geared motor on the frequency inverter, as it
reduced speeds and the associated lower cooling capacity can cause the motor to overheat.
can occur.

Brake

The available brake types with max. possible braking torques are displayed for selection. The following additional information is required to specify the brake:

Brake voltage

• 230V/50Hz/1~
• 400V/50Hz/3~
• 24V (DC)

Braking torque

at the drive motor (multiplication by the transmission ratio i results in the braking torque at the output shaft),

Manual release

for the mechanical release of the brake via a lever, e.g. for adjustment or maintenance
Further information and technical data on the brakes can be found in the PDF document Notes on selecting options

Forced cooling fan

Use of a forced cooling fan, e.g. when operating on a frequency inverter, to prevent the motor from overheating due to the
overheating of the motor due to the lower cooling capacity at reduced speeds.

Selectable forced cooling fan voltage:
400V, 50Hz 3~ (standard)
230V, 50Hz 1~

- Connection via contacts in the motor terminal box
- Protection class IP65

Incremental encoder

• The encoder is mounted under the fan cover, protected from external influences
• Protection class: IP65
• Signals: A, /A, B, /B, 0, /0
• Current consumption: 40mA / max. 90mA
• Permissible load / channel: ą 20 mA
• Pulses/revolution: selectable from 10, 25, 50, 60, 100, 200, 250, 500, 512, 1000, 1200, 2000, 2048, 2500
• Output signal TTL (RS422)
  Supply voltage: 5VDC ą 5%

For relieving pressure in the gearbox. Relieves the sealing rings and prevents leaks.

Standard version from gearbox size G3.

Other options

Fan cover with protective roof

When installed vertically, the protective roof prevents the ingress of foreign objects or liquids.
