Selection of a Commutation Initialization Method Glentek recommends using either Hall or Resolver motor commutation. If you have specific needs which preclude the use of these initialization methods, contacting your Glentek representative is a great option to discuss additional methods.
Note: For the Smart-Comm commutation method, the commutation tracks are not needed (only an incremental encoder is needed) as shown in the Current Loop Control Diagram Gamma Series on p. 142. If you are planning to use Smart-Comm, be sure to contact your Glentek representative first, and he/she can have the following variables preset at the factory before shipment.

This value must be greater than the Ramping Time. This value is in seconds. Simulated Hall Drives create simulated Hall signals from feedback devices.
Gamma Series Digital PWM Drive Manual VIEW TABLE OF CONTENTS 5.10 Drive Mode (Found at Setup -> Drive Mode) The drive can be set to operate in current (2-phase), velocity, or position mode. Current mode is always enabled. If the drive is selected to operate in 2-phase mode, it can only operate in this setting. You'll notice when you first bring this up on a new drive it will have the current mode automatically selected.
If you need to enable Encoder Fault or Encoder Reverse, the checkboxes for these options are found here. The Additional Calculations button opens another window which contains information needed by Glentek customer support to help diagnose problems.

Move the channel 2 scope probe and scope common to any two of the motor three leads to determine which BEMF waveform is in phase with the Hall U signal.

Gamma Series Digital PWM Drive Manual VIEW TABLE OF CONTENTS Auto Phasing Procedure This procedure should only be used at the initial startup of a system. Once completed, the settings can be saved as a backup, and these settings can then be restored in future systems. Future systems must be identical and wired exactly the same.

Gamma Series Digital PWM Drive Manual VIEW TABLE OF CONTENTS 5. In the Auto-phase Mode section, select Step if the motor is linear or rotary type (with limited range of motion or travel distance). Alternately, if the motor has unlimited range of motion (during auto- phasing process), it is recommended to select Continuous auto-phase mode because it helps null out any uneven inertial load on the motor shaft and produce a higher accuracy phase alignment.

Gamma Series Digital PWM Drive Manual VIEW TABLE OF CONTENTS 9. Verify that the motor phase wires are connected properly, number of poles (this is not pole pairs), and line per revolution (not the quadrature count) are set correctly. If all were correct, increase Final Current value to 60% of motor rated current.
Setup -> Commutation, then select the Feedback Config tab. Then check the Encoder Reverse box. Press Send Settings To drive and Save to NVM.

Hall state transition once motion is commanded. Phase Lead Glentek’s advanced algorithms provide automatic phase lead and eliminate the need to manually specify phase lead. These advanced algorithms ensure that the system is operating at the highest possible speed and with maximum efficiency.
Current Loop Control Diagram Gamma Series. If you are planning to use Smart-Comm, be sure to contact your Glentek sales agent first, and he/she can have these following variables preset at the factory before shipment. However, the default value in the drive will work for most cases.

Gamma Series Digital PWM Drive Manual VIEW TABLE OF CONTENTS 6.9 European Union EMC Directives Electromagnetic Compatibility Guidelines For Machine Design This section provides background information about Electromagnetic Interference (EMI) and machine design guidelines for Electromagnetic Compatibility (EMC). Perhaps no other subject related to the installation of industrial electronic equipment is so misunderstood as electrical noise.
Gamma Series Digital PWM Drive Manual VIEW TABLE OF CONTENTS In the case of servo drives, reducing the EMI source requires slowing power semiconductor switching speeds. However, this adversely affects drive performance with respect to heat dissipation and speed/torque regulation. Hardening the victim equipment may not be possible, or practical. The final and often the most realistic solution is to reduce the coupling mechanism between the source and victim.

Gamma Series Digital PWM Drive Manual VIEW TABLE OF CONTENTS If the filter is mounted excessively far from the drive, it may be necessary to mount it to a grounded conductive surface, such as the enclosure, to establish a high frequency (HF) connection to that surface.
Gamma Series Digital PWM Drive Manual VIEW TABLE OF CONTENTS Grounding High frequency (HF) grounding is different from safety grounding. A long wire is sufficient for a safety ground, but is completely ineffective as a HF ground due to the wire inductance. As a rule of thumb, a wire has an inductance of 8 nH/in regardless of diameter.
Gamma Series Digital PWM Drive Manual VIEW TABLE OF CONTENTS Shielding and Segregation The EMI radiating from the drive enclosure drops off very quickly over distance. Mounting the drive in an enclosure, such as an industrial cabinet, further reduces the radiated emissions. The cabinet should have a high frequency ground and the size of the openings should be minimized.

Gamma Series Digital PWM Drive Manual VIEW TABLE OF CONTENTS Cable intersections should always occur at right angles to minimize magnetic coupling. The encoder mounted on the brushless servo motor should be connected to the drive with a cable using multiple twisted wire pairs and an overall cable shield. Encoder cables are offered in various lengths that have correct terminations.
