7.14.6 Installation and Commissioning
7.14.6.1 Safety instructions
• Observe "Use as directed" on page 11.
• The monitoring contacts (KSO1/2) for each PMCprimo Drive2 with an -AS- option must be
looped into the control circuit. This is vital, so that a malfunction of the internal safety relay or a
cable break can be recognized.
• If the -AS- option is automatically activiated by a control system (KSI1/2), then make sure that
the output of the control is monitored for possible malfunction. This can be used to prevent a
faulty output from activating the -AS- option while the motor is running.
7.14.6.2 Application example
The following application example describes the function of the –AS- option. A PLC is controlling
the function:
1. The PLC sets the signal „activate AS“ with a digital output to a digital input of the PMCprimo
Drive2
2. The PMCprimo Drive2 triggers a program which stops the motor and goes in the motor-off
state (MO).
3. The ENABLE-signal (X3/pin 15) has to go low (0V).
4. The motor brake is activated from the PMCprimo Drive2
5. Now another PMCprimo Drive2 program sets an output and activates the option –AS
6. The PLC will get the message „AS activated“ via the monitoring contacts KSO1/2
If the PLC doesn’t gets the message „AS activated“ after setting „activate –AS“ to PMCprimo Drive2
there is a malfunction in the system.
The master contactor should be opened in this case.
