RM - Reference Mode

Purpose:

Specifies the use of an external reference signal. In all unit modes, the

SimplIQ drive sums

the reference command to the drive from two sources:

 A software command, generated internally either by a communicated command or by

a user program

 An “auxiliary” reference, may be the sum of analog input #1 and the external signals

that are derived by the auxiliary encoder (possibly using the ECAM table) or PWM

signals.

 In position mode (UM=5), the analog input is not used as a reference.

 In stepper mode (UM=3), an auxiliary reference is sets the torque value to the stepper

generator.

The RM values are as follows:

RM Value Meaning

0 The reference command is generated internally, either by the

interpreter command or by the user program.

1 The reference command is summed from the internal software

reference command and the auxiliary reference command.

Table 3-40: RM Values

Attributes: Type: Parameter, Integer

Source: Program, RS-232, CANopen

Restrictions: Defined in following notes

Default value: 0 (RS), Non-volatile

Range: [0, 1]

Unit modes: All

Activation: MO=1

Notes:

 If you are not using the auxiliary referencing option, set RM=0 to prevent A/D

noise from falsely driving the drive.

 In dual loop mode (UM=4), switching to auxiliary reference mode (RM=1) is not

allowed.

 In position mode (UM=5), RM may be changed only when the software reference

is stationary (MS ≤ 1). In speed mode (UM=2) RM may be changed at any time.
