Hi, 
 These servos are controlled by sending a Pulse width Modulation (PWM) signal. For the nRF51 the best starting point will be the PWM Library Example .
It’s located in the folder 
 <SDK_InstallFolder>\examples\peripheral\pwm_library 
 
 Try with a period of 20000L, and set the duty cycle to 5% and 10% for min and max servo position. 
 Code snippets: 
 app_pwm_config_t pwm1_cfg = APP_PWM_DEFAULT_CONFIG_1CH(20000L, PWM_PIN);




while (app_pwm_channel_duty_set(&PWM1, 0, 10) == NRF_ERROR_BUSY);
