6.2.5 Analog input scale (Velocity scale)
This parameter sets analog input sensitivity for velocity reference used when drive operates in Velocity
mode. Units for this parameter are RPM/Volt. To calculate value use following formula:
Vscale = VelocityMax / Vin max
Velocitymax
maximum desired velocity in RPM
Vin max max voltage fed to analog input at Velocitymax
Example: Velocitymax = 2000 RPM
Vin max = 10V
Vscale = Velocitymax / Vin max = 2000 / 10V = 200 RPM / Volt -> value to
enter.
6.2.6 ACCEL/DECEL Limits (Velocity mode only)
The ACCEL setting determines the time the motor takes to ramp to a higher speed . The DECEL
setting determines the time the motor takes to ramp to a lower speed. If the ENABLE ACCEL\DECEL
LIMITS is set to disable, the drive will automatically accelerate and decelerate at maximum
acceleration limited only by current limit established by the CURRENT LIMIT setting.
6.2.7 Reference (Velocity mode only)
The REFERENCE setting selects the reference signal being used.
Select Internal only when you using drive’s built-in digital signal generator for tuning purposes .
Select External for normal operations.
6.2.8 Reset Option
RESET OPTION selects the type of action you must take to reset the drive after a FAULT signal has
been generated by the drive. ON DISABLE clears the fault when the drive is disabled. This is useful if
you have a single drive and motor connected in a simple servo system. The ON ENABLE option
clears the fault when the drive is re-enabled. Choose ON ENABLE if you have a complex servo
system with multiple drives connected to an external controller. This makes troubleshooting easier
since the fault will not be reset until the drive is re-enabled. Thus, a technician can more easily
determine which component of a complex servo system has caused the fault.
6.2.9 Steps per Revolution (Step and Direction mode only)
Steps per revolution defines how many pulses must be supplied to the step and direction input to
make one full revolution of the motor shaft. This number can be negative effectively reversing motor
rotation. Used also to set “gear” ratio if drive following a master motor.
6.2.10 Step input type (Step and Direction mode only)
Two types of inputs are possible: Step and Direction (select S/D) or master encoder. If master encoder
is selected drive expects full quadrature A & B signals. Refer to hardware manual for specifications on
Master encoder pulse train input.
