94 Application macros

Dual setpoint with PID and constant speeds
This macro configures for applications with 2 constant speeds, active PID and PID
alternating between two setpoints using digital inputs. Set PID setpoints (internal to
the drive) using parameters 4011 (
SET
1) and 4111 (
SET
2). The digital input DI3 selects
the setpoints.
For more information see Default values with different macros on page 279 .
