Quick Setup Parameters
The following is a list of the Quick Setup parameters you must check before starting the drive. Set
only the ones marked with “x” in the table below, under the intended mode of operation.
V/Hz SV Vector
Control Mode Select the intended operating mode x x x
Max Speed Motor RPM at full process speed x x x
V/F shape Usually Linear. Choose fan curve only for fans x
Motor Current Motor full load current from motor nameplate x x x
Motor Base Freq Motor nameplate frequency x x x
Motor Voltage Motor nameplate voltage x x x
Nameplate RPM Motor nameplate RPM x x x
Motor Poles See Note x x
Pulse Enc Volts Set between 10-20V to match encoder x
Encoder Lines Pulses per Revolution of encoder x
Encoder Invert Changes polarity of encoder feedback x
Autotune Enable Drive will Autotune if started x x
Mag Current Enter the No-Load Amps from the motor nameplate x x* x*
* if perfoming a Stationary Autotune.
NOTE Some of the parameters are product code dependent, that is, they are different for each
frame size and power rating. For example, the unit will be set for either 50Hz or 60Hz
operation:
Motor Poles for 60Hz 2 poles = 3600 rpm, 4 poles = 1800 rpm, 6 poles = 1200 rpm
Motor Poles for 50Hz 2 poles = 3000 rpm, 4 poles = 1500 rpm, 6 poles = 1000 rpm
Autotune
Ensure that MAX SPEED is greater than NAMEPLATE RPM for a successful autotune.
In the QUICK SETUP menu, set AUTOTUNE ENABLE to TRUE.
On the 890CD keypad select LOCAL mode. Set SETPOINT (LOCAL) to 0.0%.
Press the green RUN button. The drive will begin autotuning. The drive will stop without errors if
autotune is successful.
Go to SYSTEM::SAVE CONFIG::APPLICATION and UP arrow to save your settings.
