Elevator Core Reference Guide

The drive can store a backup of the user parameter settings, this is useful in the event of someone inadvertently adjusting the drive operational parameters and allows for the parameter settings to be returned exactly as per the original installation.

Once the drive has been programmed for the application, setting parameter P11-01 to a 1 will save the drive parameters as user default parameters.

The value entered in parameter P11-02 determines which parameter groups are accessible by the user by default if:

Level 1 access includes groups 0 through to group 11.

Level 2 access includes groups 0 through to group 12.

The code for Level 2 can be changed by the user by setting the desired value into parameter P11-04.

Enter your chosen access code here (> 0) which once set must be entered in P11-02 to access parameter Group 2.

Once set this parameter will become hidden until the same value is entered into P11-02.

Selects the type of PWM modulation.

Higher switching frequencies reduce the audible ‘ringing’ noise from the motor and improve the output current waveform at the expense of increased drive losses.

This parameter defines the minimum switching frequency which the drive will use when the drive auto- switches down the switching frequency (Based on Heatsink Temperature and motor current) in order to reduce the losses and heat from the power stage.

Reserved

Select the motor phase orientation.

If P11-11 is set >0, the variable selected in P11-12 is multiplied by the factor entered in P11-11, and displayed whilst the drive is running with a ‘c’ to indicate the customer scaled units.

P11-11 & P11-12 allow the user to program the drive to display an alternative output unit scaled from an existing parameter, e.g. to display speed in meters per second based on the output frequency.

Source to be multiplied by P11-11

Resets the internal fan run-time counter to zero (as displayed in P0-55).

Sets how the drive fan should operate when the turn on conditions are reached.

This parameter defines the fan run time after the drive has stopped running when the temperature in P0-48 reaches 45°C.

Setting to 1 resets the internal energy consumption kWh meter to zero (as displayed in P13-57 and P13-58).

This defines the total number of run time hours which must elapse before the Service indicator output comes on.

For example if terminal DA1 is set to Digital Output and Parameter P1-15 is set at 14: Service Indicator then once the value in this parameter has been met the Digital Output changes to Logic 1.

Displays the number of hours remaining on the service counter before the next service is due

A negative value shows the service overdue hours.

When this parameter is set to 1, the internal Service time interval counter (P11-17) is reset.

Sets the trip threshold resistance for the connected motor thermistor.

Sets the trip reset threshold resistance for the connected motor thermistor.

Internal Use only

While enabled (setting 0) this function checks that the control commands sent from the controller to the drive are in the following expected order:

If the order differs then the drive will trip Odr-Er.

If set to 1 then this feature is disabled and the drive will not trip.

Sets the time that when the drive stops the Safety Chain inputs (STO1 and STO2) must open. If the STO inputs do not change state then the drive will trip Sto-S.

This is used to detect a short circuit of the drive STO ports.

Setting P11-24 to 0.0 will disable this function.

This parameter allows you to disable the Sto-L trip by setting the value to 1. So when both STO terminals (STO1 & STO2) are opened while the drive is running the drive will not trip By default the Sto-L trip is enabled.

It is recommended that you keep the Sto-L trip enabled to show if there is a fault with the Safe Torque Off Ports (STO1 & STO2).
