HEIDENHAIN MANUALPLUS 620 - 2.5.10 Handwheels

98 HEIDENHAIN Technical Manual MANUALplus 620
2.5.10 Handwheels
All handwheels are available with and without detent. For handwheels with
detent, the cogging torque prevents movements of the handwheel due to
motions or vibrations of the machine. On handwheels without detent, this is
prevented by a defined holding torque.
Handwheels with detent feature 100 detent positions per revolution, i.e. every
3.6°. The machine manufacturer defines the increment via the machine
configuration.
