7. Setting the inputs MOTOR CURRENT OFF, MOTOR STOP or RESET is no
sure separation in the emergency case.
The voltage supply has to be interrupted for safely switching off the drive.
8. For high stepping frequencies, the control pulse frequency should not be
interrupted suddenly. Also avoid maintaining the control pulse input at the low-
level (L).
9. If the stepper motor misses steps, decrease the acceleration or the maximum
frequency values.
10. The motor should not be driven externally, because it would operate as a
generator and deliver energy to the SINCOS.
11. If the SINCOS power stage switches to overtemperature, make sure that
sufficient cooling measures are installed.
Perhaps the supply voltage could be reduced in order to get lower losses. The
stop current should not be set to more than 50% of the drive current (check
potentiometer I
STOP
setting).
12. The SINCOS surface may reach temperatures of 70 °C.
Danger of injury if touching the surface !
8 Warranty
The SINCOS stepper motor power stages are subject to Phytron's legal warranty. Phytron
will repair or exchange units which show a failure due to defects in material or caused by
the production process. This warranty does not include damages which are caused by the
customer, as there are, for example, not intended use, unauthorized modifications, wrong
treatment or wrong wiring.
9 ESD Protective Measures
All the products which we deliver have been carefully checked and submitted to a longterm
test. To avoid the failure of components sensitive to electrostatic discharge (ESD), we
apply a great number of protective measures during manufacturing, from the component
input check until the delivery of the finished products.
Warning:
Manipulation of ESD sensitive devices must be effected by respecting special protective
measures (EN 61340 – 5). Only return the devices in adapted packaging.
Phytron's warranty is cancelled in case of damages arising from improper
manipulation or transportation of ESD sensitive modules and components.
