Elevator Core Reference Guide

Sets the motor control mode depending on the motor type used.

For Induction (Geared) type elevator Motors (P4-01 = 0,1,2) enter the motor rated voltage as shown on the motor nameplate. If set to 0 voltage compensation is disabled.

When operating Gearless Permanent Magnet Motors in closed loop this value can be set to 0.

When operating Gearless Permanent Magnet Motors (P4-01 = 3) in open loop (P6-05 = 0) the Phase-to-Phase back emf voltage at rated speed must be entered in this parameter.

Enter the Rated (nameplate) current of the motor.

This value must be entered to protect the motor.

Enter the rated (nameplate) Frequency of the motor.

Enter the number of motor poles as shown on the motor nameplate.

Enter the rated (nameplate) speed of the motor in rpm.

When controlling a Geared Induction Motor: Allows drive calculation of the rated slip of the motor (in V/F Mode only).

All motors: Changes all speed related parameter values to rpm. This parameter is also required for operating in Linear units.

Enter the rated (nameplate) Cos-Phi of the motor.

If value not available leave at default.

Used to select the required Auto-tune mode.

To perform an Auto-tune the following conditions must be fulfilled:

Voltage boost is used to increase the applied motor voltage at low output frequencies, this can help improve low speed and starting torque.

When operating in V/F mode (P4-01 = 2), this parameter in conjunction with P4-11 sets a frequency point (as a % of P4-04) at which the voltage set in P4-11 (as a % of P4-02) is applied to the motor. Care must be taken to avoid overheating and damaging the motor when using this feature.

Used in conjunction with P4-10

Only effective when operating without an encoder.

Allows a Boost current to be applied at start-up and low frequency (limit defined by P4-13), as a % of the motor rated current (P4-03). Injecting some additional current into the motor at low speed to ensure that rotor alignment is maintained and improving operation during starting and low speed with additional holding torque.

Only effective when operating without an encoder.

Frequency range for applied boost current (P4-12) as a % of motor rated frequency (P4-04). This sets the frequency cut-off point above which boost current (P4-12) is no longer applied to the motor.

Only effective when operating without an encoder.

Allows a Boost current to be applied at stop and low frequency (limit defined by P4-15), as a % of the motor rated current (P4-03). Injecting some additional current into the motor at low speed to ensure that rotor alignment is maintained and improving operation during stopping with additional holding torque.

Only effective when operating without an encoder.

Frequency range for applied boost current (P4-14) as a % of motor rated frequency (P4-04). This sets the frequency cut-off point below which boost current is no longer applied to the motor.

Additional flux during braking/regen

Setting the parameter to 0.0s means the function is disabled. This parameter helps in reducing the noise in the lift car when the motor brake is applied due to the immediate removal of current. Increasing this value reduces audible noise, setting too high can result in reduced torque and rollback during stopping.

This parameter has no effect when operating in an IM or V/F control mode (P4-01 = 0, 1 or 2) and the torque reduction time is fixed at 100ms.

When operating in Vector Speed motor control modes (P4-01 = 0, 1, 3), this parameter defines the maximum torque limit when motoring.

If this limit is reached for 1 second the drive will trip Sp-Err.

When operating in Vector Speed motor control modes (P4-01 = 0, 1, 3), this parameter defines the maximum torque limit when regenerating.

If this limit is reached for 1 second the drive will trip Sp-Err.

The elevator can have different travel speeds in each direction under the same load. This is called slip (difference between synchronous speed and asynchronous speed).

For example if the nominal speed of a motor is 1430rpm. With an empty car in the downwards direction the speed is 1430 rpm. In upwards direction the speed is 1570rpm.

To eliminate this use P4-20 when in motoring mode (positive torque direction).

As per P4-20 use this parameter when in regeneration mode.

Used to set the trip reaction when a motor thermistor fault occurs.

For Geared (Induction) and PM motors: phase to phase stator resistance value in ohms as measured following an Auto-tune.

Should be left at the value measured by the Auto-tune.

For Geared (Induction) motors: phase to phase rotor resistance value in ohms as measured following an Auto-tune.

Should be left at the value measured by the Auto-tune.

For Geared (Induction) motors: phase stator inductance value. For Gearless (Permanent Magnet) motors: phase d-axis stator inductance in Milli Henry (mH).

Should be left at the value measured by the Auto-tune.

For Gearless (Permanent Magnet) motors: phase q-axis stator inductance in Milli Henry (mH).

Should be left at the value measured by the Auto-tune.

For Geared (Induction) motors only: magnetizing / no load current, before Auto-tune,
