Elevator Core Reference Guide

Changes the direction of the incremental signals of the encoder feedback signal.

Sets the number of Pulses Per Revolution for the encoder according the Encoder nameplate/datasheet. This value must be set correctly to guarantee proper operation of the drive when Encoder feedback mode is enabled (P6-05 = 0).

Typically values for Incremental encoders are 512, 1024, 2048, 4096

Set the Encoder type from the table below.

Enables or disables encoder feedback. When the encoder is disabled it is referred to as open loop and when the encoder is enabled it is referred to as closed loop.

Helps in situations where there is noise on the Incremental encoder cables, and also allows for setting of higher speed loop gains.

Helps in situations where there is noise on the Incremental encoder cables, and also allows for setting of higher speed loop gains.

Populated measurement of the stationary encoder offset measurement when setting the Auto-tune (P4-08) to either setting 2,3,4 or 5.

This value can also be entered manually.

Real-time position of the encoder.

In open or closed loop operation this parameter defines the maximum permissible speed error (as % of the motor rated speed P4-06) between the Post-ramp Speed Controller Reference and the estimated rotor speed (open loop) or encoder feedback speed (closed loop) as calculated by the motor control algorithms. If the speed error exceeds this limit (for the time set in Parameter P6-12 Speed Error Trip Detection Time), the drive will trip Sp-Err.

Figure 1. Speed Error Detection in Open Loop Operation

Example below was on an application with a 1370 rpm rated speed motor, 0.3s detection time and a 0.1% speed error trip level, where 0.1% equates to 1.37rpm (0.001*1370rpm) for 0.3s after which the drive will trip Sp-Err.

In Closed loop operation this parameter defines the maximum permissible speed error between the encoder feedback speed value and the estimated rotor speed calculated by the motor control algorithms. If the speed error exceeds this limit (for the time set in Parameter P6-12 Speed Error Trip Detection Time) , the drive will trip Sp-Err.

Used in Conjunction with P6-11 (Speed Error Trip Level) to define to allowed time when the speed is above the value in P6-11 before tripping.

Displays the Error Codes for the Universal Encoder Module.

Information on the error codes and can be found in the troubleshooting section.

Displays Encoder Communication Signal quality.

If the signal quality is poor this will lead to dropped messages and could lead to poor motor performance.

This parameter is only available for Digital Encoders. When using a TTL or HTL encoder it will always disaply 0.00%.
