The SERVOSTAR CD-Lite also has an automatic analog input zeroing function. Invoking the ANZERO command while the drive is enabled or disabled samples motor velocity over a 32 ms period and updates ANOFF1 accordingly to cancel out analog input offset. This command uses an internal offset mechanism that has finer resolution than ANOFF1 is capable of providing.The opto-isolated Remote Enable input (REMOTE) provides a hardware drive enable switch. This 12-24 VDC input disables or enables the power stage output to the motor. The signal must be customersupplied to get the drive to enable (in combination with other parameters; ACTIVE) and operate. Tapping the signal off the logic supply (C5) is not recommended. The toggling of this switch also initiates an attempt to recover from a fault condition.

The SERVOSTAR CD-Lite provides a drive ready/drive up output in the form of a relay (RELAY) output. The relay (RELAY) output is controlled by the SERVOSTAR CD-Lite’s microprocessor. There is a software switch (RELAYMODE) that configures the relay (RELAY) output to act as a ‘Drive Ready’ or ‘Drive Up’ indicator: If RELAYMODE = 0, the relay is closed when the drive is error free and ready to run. This is a ‘Drive Ready’ configuration.

Core Processors

 A 40 MHz embedded Controller and a 40 MHz DSP controller are the heart of the SERVOSTAR CDLite. They use its internal operating system to monitor inputs, adjust outputs, communicate serially, maintain servo control, and monitor faults. The flash memory firmware that controls the core processor and gives the SERVOSTAR CD-Lite its operating characteristics is saved in EPROM. The version number of the firmware can be read using the VER command. When calling Danaher Motion Customer Support, be sure to have the firmware version number readily available. The most recent version of firmware is available for purchase and is easily field-upgradable through a PC. It can be obtained by contacting a Danaher Motion sales representative or by contacting the Danaher Motion Customer Support.

Since current and torque are proportional in a Permanent Magnet (PM) motor, the current loop is often referred to as the torque loop. The function of the current loop is to regulate motor current as directed by a current command signal. The current command signal from the microprocessor can either come from a direct user input (OPMODE 3) or from the output of the velocity loop. There are actually three current loops, one for each motor phase. Each current loop receives its own command input from the commutation loop. The SERVOSTAR CD-Lite uses a fully digital, pole placement current loop with high bandwidth and a current loop sampling rate of 16 kHz (62.5 µs). All coefficients of the current loop are digitally calculated inside the drive for a given set of motor and drive characteristics. The current loop also includes adaptive gain terms to compensate for some non-linear effects. The current loop incorporates electrical isolation for protection from the high-voltage BUS. These current loops also convert the output voltage to a Pulse Width Modulated (PWM) signal providing the highest efficiency possible. The PWM center frequency can be 8 or 16 kHz according to the drive size.
