The motor needs to move freely while you set the commutation. If the motor cannot move freely, it results in an incorrect point of reference for commutation. Incorrect commutation can cause unexpected movements and leads to poor efficiency.

UNINTENDED OPERATION |
|
oPerform the test movement without coupled loads. oInstall linear motors in a horizontal position. oVerify that the holding brake is released before performing the test movement. oTake into account that the limit switch signals are not evaluated during the test movement. oVerify that a functioning button for emergency stop is within reach. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
The function Wake & Shake corresponds to a test movement to automatically determine the commutation angle.
Wake & Shake is used if the commutation angle cannot be determined by means of other mechanisms, for example, via the SinCos Hiperface interface, Hall effect signals or the resolver.
Wake & Shake is only available for motor encoders.
Wake & Shake movement is started in the following cases:
oWith analog encoders with the interface SinCos 1Vpp (without Hall):
After enabling the power stage for the first time (after starting the drive).
oWith analog encoders with the interface SinCos Hiperface and encoders with the interface Resolver:
During the commissioning via the wizard of the commissioning software.
Use the parameter WakesAndShakeGain to adapt Wake & Shake to your mechanical system.

Gain for wake and shake. If wake and shake did not work properly, this parameter can be used to adapt the dynamics of the wake and shake procedure. Value >100 %: Increased dynamics which leads to less motor movement. Value <100 %: Reduced dynamics which leads to more motor movement. Type: Unsigned decimal - 2 bytes Write access via Sercos: CP2, CP3, CP4 In increments of 0.1 %. Setting can only be modified if power stage is disabled. Modified settings become effective immediately. |
