2.2 List of parameters
Re bit 08:
For bit = 1 and with the SDI safety function activated, the following applies:
- During pulse suppression, monitoring is switched off and the status signal indicates inactive.
For bit = 0 and with the SDI safety function activated, the following applies:
- Monitoring continues during pulse suppression. The status signal indicates active and the system goes into the STO
state.
Description: Setting for clock cycle synchronous communication between PROFIdrive controller and Control Unit.
The parameter is only relevant, if the safety-relevant motion monitoring functions integrated in the drive have been
enabled (p9601.2 =1 ).
If a PROFIdrive controller exchanges process data in clock cycle synchronism with the Control Unit, then p9510 must
be set to 1. This also applies if the drive itself does not exchange process data in clock cycle synchronism.
Examples for clock cycle synchronous communication:
- clock-cycle synchronous control for the motion control (e.g. SIMOTION).
- clock-cycle synchronous PROFIsafe master (e.g. SIMATIC S7-400F).
Value: 0: Communication not isochronous
1: Communication isochronous
Notice: As of firmware version 2.6, the parameter has no effect.
Description: Sets the clock cycle time of the actual value sensing for safe motion monitoring.
Setting criteria if the motion monitoring functions are executed with an encoder.
- A slower clock cycle time reduces the maximum permissible velocity - however, it ensures a lower load of the
Control Unit for safe actual value sensing.
- The maximum permissible velocity which, when exceeded, can mean that errors occur during safe actual value
sensing, is displayed in r9730.
- The isochronous PROFIBUS clock cycle is used as a clock cycle time for actual value sensing with a setting of 0
ms; the setting is 1 ms if isochronous operation is not being used.
Setting criteria if the motion monitoring functions are executed without an encoder:
- The actual value sensing clock cycle must be set to the same value as the current controller clock cycle (p0115).
Dependency: Refer to: p0115
Note: The parameter is only active for drive-based motion monitoring functions (p9601.2 = 1).
The monitoring clock cycle from p9500 must be an integer multiple of this parameter.
In the case of motion monitoring functions with encoder, the clock cycle time for actual value sensing must be an
integer multiple of the current controller clock cycle and at least 4 times slower than the current controller clock cycle.
A factor of at least 8 is recommended.
The clock cycle time of the actual value sensing should not be set to more than 8 ms.
A change only becomes effective after a POWER ON.
