Function modules 7.9 Basic positioner

Stop cam minus active (r2684.13)

Stop cam plus active (r2684.14)

These status signals indicate that the stop cam minus p2569 or stop cam plus p2570 were reached or passed. The signals are reset if the cams are left in a directly opposing the approach direction.

Axis moves forwards (r2683.4)

Axis moves backwards (r2683.5)

Axis accelerates (r2684.4)

Drive decelerates (r2684.5)

Drive stationary (zero speed) (r2199.0)

These signals display the current motion status. If the actual absolute speed is less or equal to p2161, then the status signal "drive stationary" is set - otherwise it is deleted. The signals are appropriately set if jog mode, reference point approach or a traversing task is active.

Cam switching signal 1 (r2683.8)

Cam switching signal 2 (r2683.9)

The electronic cam function can be implemented using these signals. Cam switching signal 1 is 0 if the actual position is greater than p2547 - otherwise 1. Cam switching signal 2 is 0 if the actual position is greater than p2548 - otherwise 1. This means that the signal is deleted if the drive is located behind (after) the cam switching position. The position controller initiates these signals.

Direct output 1 (r2683.10)

Direct output 2 (r2683.11)

If a digital output is parameterized, the function "direct output 1" or "direct output 2", then it can be set by a corresponding command in the traversing task (SET_O) or reset (RESET_O).

Following error in tolerance (r2684.8)

When the axis is traversed, closed-loop position controlled, using a model, the permissible following error is determined from the instantaneous velocity and the selected Kv factor. Parameter p2546 defines a dynamic following error window that defines the permissible deviation from the calculated value. The status signal indicates as to whether the following error is within the window (status 1).

Target position reached (r2684.10)

The status signal "target position reached" indicates that the drive has reached its target position at the end of a traversing command. This signal is set as soon as the actual drive position is within the positioning window p2544 and is reset, if it leaves this window.

The status signal is not set, if

●Signal level 1 at binector input p2554 "signal traversing command active".

●Signal level 0 at binector input p2551 "signal setpoint static".

The status signal remains set, until
